Vickers HRCs Simplify Remote Control of Work Functions and Improve Productivity

DescriptionHRCs (hydraulic remote controls) areavailable in hand, foot and mechanicallyoperated versions, designed for pilotpressure actuation and control ofremotely located directional valves.

They are intended for mobile andindustrial applications in which hydraulicpilot operation of system components is tobe controlled from one operator station.On vehicles, the HRCs are typicallyinstalled in seat armrests or a console.

OperationThe 30 design HRCs operate on inputflows up to 16 L/min (4.2 USgpm) andpressures up to 110 bar (1600 psi) or150 bar (2175 psi), dependent on themodel and the type of response requiredfor the application. HRCs require inputpressures equal to the maximumrequired output pressures, andpreferably a minimum of 10 bar (145 psi)higher to assure fast response. From theinput pressure an HRC creates reducedoutput pressures that vary proportionallywith lever or pedal stroke, applying thepressures to main directional valvescontrolling speed and direction ofhydraulic actuators. Full details aregiven in this publication.

Features and BenefitsLow Effort, Precise Control� Very little operator effort results in less

fatigue and more productivity fromman and machine.

� Excellent pressure metering capabilityallows precise control of workfunctions and less wear-and-tear ofthe application.

� Precise control in circuits subjected towide variations in pressure. Thiscontrol is assured by using an ACX2supply unit; see opposite page.

Freedom of System Design� Single-station control of widely placed

directional valves readily achieved.� In a vehicle, for example, an HRC is

easily mountable in the cab orelsewhere because it is compact andeliminates the cumbersomemechanical linkage found in manyapplications.

� Allows ergonomic operatorworkstation design to be achieved byutilizing the low noise, safe oiltemperature, and removing firehazards from the workstation. This inturn leads to a safer, cleaner, andmore operator friendly environment.

� Allows main-stage directional valvesto be mounted for optimum piping,quietness and heat dissipation.

� Wide range of output characteristicsallow HRC to be perfectly matched tothe main-stage valve.

Low Noise Level� The use of an HRC allows better

insulation between the cab andengine because there is no longer aneed of holes through the cab wall forlinkage to the main valve.

� Low hysteresis provides highlycontrollable and repeatable control ofactuator, and reduces vehicle shockand subsequent noise.

Enhanced Operator Safety� The HRC needs only a relatively low

working pressure, about 30 bar (435psi). This lessens the risk to theoperator from any pipe failure.

Dependable, Quality Products� Robust hydro-mechanical design.� Maximum reliability born of years of

field experience.� All electrical components used in

multi-function operator handles aretested to ensure long and trouble freelife.

� Easy servicing.

Additional Features and Benefits ofthe 30 Design� Improved control sensitivity from large

reductions of dead band in alldirections.

� Compact electro-magnetic ormechanical detents available asoption on most models.

� Wide range of stylish ergonomicallydesigned hand actuators that mayinclude multiple electrical switches.

� Stroke limiting devices available onmost models.

� Flexible aluminum valve body designallows for many special logic featuresto be incorporated into the product.

HRC1-S SeriesThis is the most simple of the wholeproduct family, and is typically used tocontrol a diverter valve or power clutch,or similar single acting functions.

The whole HRC family of products isbased upon the pressure reducing valveconcept, using a constant inlet pressure,and providing a variable outlet pressureas a direct result of the actuatingmechanism position.

The entire product range uses the samealuminum body concept, and all othermetallic external parts are chemicallytreated using a black oxide process.This enhances the appearance andeliminates the need for any painting.Other common parts throughout therange are the spring capsule, guide andpusher arrangements.

Model Code

Features� Lightweight flexible design.

� Adjustable Guide and Pusher

This option permits the metering spoolstroke to be limited, in order to limit thepilot pressure sent to the outlet of theHydraulic Remote Control. This device istypically used when the HRCs aresupplied with high pressure, but it isdesirable to ensure that the maximumoutlet pressure is controlled below thisinlet pressure. It may also be used to setdifferent cylinder lowering speeds bylimiting the spool stroke on the main-stagevalve.

HRC2-S SeriesThe “S” series is a single function valvethat may be fitted with many differentstyles of hand operated levers. This unitmay be used as a single valve orassembled into a bank of HRC2-Svalves where more than one valve spoolneeds to be controlled. The valve’sdesign allows a single pump supply andtank return line to be used in a bank ofvalves, and may be connected at eitherend of the assembly. The valves may beassembled into banks of up to 8.

HRC2-LV SeriesThe “LV” series valves are single-function valves, with all the flexibility ofthe HRC2-S models, but with theadditional option of 12 or 24V DCelectrical latching detents.

FeaturesMany optional features are available forthis product series such as:� Three-position Mechanical Detent

allowing the control actuator to beheld in the neutral and fully shiftedpositions.

� A Frictional Lock Device to allowcontinuous holding of the controlactuator at every position of thestroke.

� A Pull-to-release Safety Device toensure actuator is not accidentallyoperated. Lever may only be operatedafter lifting the security collar on theactuating lever.

� Adjustable Guide and PusherThis option permits the metering spoolstroke to be limited, in order to limit thepilot pressure sent to the outlet of theHydraulic Remote Control. This deviceis typically used when the HRCs aresupplied with a high pressure, but it isdesirable to ensure that the maximumoutlet pressure is controlled below thisinlet pressure. It may also be used toset different cylinder lowering speedsby limiting the spool stroke on the mainstage valve.

Features� Electromagnetic detents, available in

12 or 24V DC versions.� Detent pre-feeling to provide operator

feedback prior to detent latch.

HRC4-H SeriesThe “H” series is a double function valvefitted with two hand operated actuators.It is typically used to control two doubleacting spools, with each actuator beingassigned to different spools. The valveis typically fitted with ball type handleactuators.

Model Code

FeaturesOptional features are available for thisproduct series, such as:� Three-position Mechanical Detent

allowing the control actuator to beheld in the neutral and fully shiftedpositions.

� Adjustable Guide and PusherThis option permits the metering spoolstroke to be limited, in order to limitthe pilot pressure sent to the outlet ofthe Hydraulic Remote Control. Thisdevice is typically used when theHRCs are supplied with a highpressure, but it is desirable to ensurethat the maximum outlet pressure iscontrolled below this inlet pressure. Itmay also be used to set differentcylinder lowering speeds by limitingthe spool stroke on the main stagevalve.

The Hydraulic Remote Control loadervalve is a development of existing HRCtechnology and a new compactelectromagnetic detent arrangement.The valve is a combined HRC2(stackable type valve) and a HRC4(joystick type valve) withelectromagnetic detents, packaged in asingle manifold-style block. Thepackage was specifically designed forwheeled and tracked loaders.

Some manufacturers currently fit anHRC control package that consists of 3sectional (HRC2) style HRCs, as this isthe preferred method of control in somemarket areas. If this is the case, we offera suitable solution using the compactelectromagnetic detent developmentwhich can be packaged with the samefunctionality into an HRC2-LV stackabletype valve. See HRC2-LV section of thispublication for more details.

This package can be further enhancedby the use of the new ergonomicanatomic handle that has beendeveloped for the standard HRC productrange. This provides the machinebuilder with both the modernergonomics required for today’s cabdesign, as well as the ability to have upto 5 electrical switches fitted into thehandle that may be used to control amultitude of machine functions.

HRC7 Float SpoolThis provides a 7th function within the valve package, typicallyto provide “float” function on the machine. This facility isavailalble in two options:1. Port 7 vents when float spool pressure setting is reached, or2. Port 7 is vented until float spool pressure setting is reached.

Features Benefits

Compact Electromagnetic Detent Provides a very compact package due to the electromagnetic detentsbeing located in line with the operating spool center lines. Ergonomic and aesthetically good looking for operator area design.

Flexible Aluminum Manifold Package 1. Provides a compact monobloc design that encompasses both adouble axis (HRC4) and a single axis (HRC2) in a single block.

2. Circuit logic elements such as pressure reducing valves, float spooloptions, etc., can be included within the package design.

3. No leakage between sections.

Single Pressure and Tank Line Connections Less plumbing and thus lower installed cost on the machine.

Wide Range of Electrical Switch Configurations Actuators can be fitted with up to 5 electrical switches in many differentconfigurations. See pages 37, 38 and 39.

Adjustable Detent Pre-feeling Allows the operator to have feedback through the operating lever as heapproaches the detent point.

Free Use of Second Axis when First is Detented Once the first axis has been placed into a detented position, the otheraxis of the valve can still be operated in free fall condition. This provideshighly controllable and proportional control of the actuator on thenon-detented axis.This is a mandatory requirement for tandem circuits.

System Design and Sizing

Output Control PressureOne of the key features of HydraulicRemote Controls is their ability toprovide improved operator control of themachine function by minimizing theamount of HRC actuator deadband, thusincreasing the effective control range ofthe valve actuator lever.

In order to achieve this feature, it isnecessary to size the output pressurecharacteristics of the Hydraulic RemoteControl.

The ideal situation is to have the HRCpressure characteristic provide an initialforce on the main-stage spool that willshift it to a position where the load is atthe threshold of moving. This pressure isrequired to overcome the timing of thedirectional valve, and the centring springforces in the main-stage valve. Thispressure is referred to as the initialpressure.

The maximum output pressure isnormally determined by the pressurerequired to move the main-stage spoolto its fully shifted position. This pressureis referred to as the final pressure.

For design flexibility, four basic outputpressure characteristic curves areavailable:B** Proportional rise with a forced rise

to supply pressure at the end of theactuator stroke.

C** Proportional rise without a forcedrise to supply pressure at the endof the actuator stroke.

D** Proportional rise with a pressurerise gain change, and without aforced rise to supply pressure atthe end of the actuator stroke.

E** Proportional rise with a pressurerise gain change, and with a forcedrise to supply pressure at the endof the actuator stroke.

The released spring capsulesassemblies are available in a wide rangeof initial and final pressure forms to allowideal matching to the main-stagecharacteristics.

Please Note:The spring capsules are factory setusing computer controlled spring testingequipment and therefore we stronglyrecommend that you do notdisassemble the units in the field, butobtain replacement capsules as andwhen required.

The output characteristics provide nooutput pressure until 2.5 degree (15%)of lever actuator has been reached. Thisis a safety feature and ensures that nofunctions are operated due to operatorbumping the control levers.

If a separate relief valve is employed inthe circuit to limit the pressure of theHRCs, it should be set at least 10 bar(140 psi) above the “final pressure”characteristic of the spring capsule.Failure to do this may result in systemresponse problems.

Supply Flow and Typical CircuitsThe supply flow requirements should bebased upon the following criteria:a) The number of simultaneous

functions to be controlled.b) The displacement of the main-stage

directional control valve.c) The shift time of the main-stage

spool.

The following is a guide to sizing therequired flow requirements.

Internal LeakageThe internal leakage of the productsusing an SAE20 fluid at a temperatureof 50� Celsius (122� Farenheight), withan inlet pressure of 40 bar (580 psi) isas follows:HRC4 Less than 90cc/min

(0.024 US gpm)HRC2 Less than 45cc/min

(0.012 US gpm)HRC1 Less than 22cc/min

(0.006 US gpm)

As these values are very low, it isunnecessary to consider them whilecalculating flow requirements.

Note:The maximum output flow from the HRCis approximately 16 L/min (4.2 USgpm)

Supply Flow From Dedicated PumpThere are various methods of supplyingthe flow to the Hydraulic Remote Control.The most common and generallyrecommended is a separate pump. In allapplications, filtration of 10 �m nominal(25 �m absolute) is recommended on thesupply flow to the HRC. Fluctuation ofsupply pump pressure will not generallycause the HRC output pressure to vary.

Supply Flow From ACX2 PilotPressure Supply UnitAn alternative method is to obtain thesupply pressure flow from the mainsystem when using an open centercircuit. This may be achieved by usingthe Vickers ACX2 pilot pressure supplyunit. This unit may be fitted with anoptional pre-charged accumulator. Theunit has the facility to be connected withtwo circuits (two pumps) and hasintegral high pressure shuttle valves.

A minimum pressure drop of 7 bar (100psi) is required from the circuit containingthe second pump (i.e. directional controlvalve circuit) to ensure correct operation ofthe ACX2 unit.

Transient Flow

Supply Flow From SPX ValveIn a circuit where the flow is lower than 90L/min (24 USgpm) and the workingpressure is lower than 250 bar (3500 psi),the Vickers SPX priority valve with integralunloading function is an ideal choice.

This unit follows the same principles asany priority valve, in that it sends the flowto the HRC unit as its first priority, untilsuch time as the maximum pressure isachieved. At this time the priority spoolinside the SPX valve shifts to a positionthat allows the flow to be fed to the otherservices. This continues until the pressureon the HRC line reaches 5 bar (70 psi)below the maximum value, at which timethe spool returns to give the priority backto the HRC valve.

When the machine functions are in astand-by condition, the excess flow issent directly to the reservoir with a verylow pressure drop, and thus provides anenergy efficient solution. In this conditionthe pressure in the HRC lines ismaintained by the accumulator fitted tothe SPX valve.

The flow taken by the SPX unit to supplythe HRC circuit is very low and thereforeyou should not experience any interactionproblems on the other services.

Safety and Energy ConservationConsiderationsIn some applications it may be desirableto have the controls inactive, or ensurethat heat generation and pressure lossesare kept to a minimum during inactiveperiods. This may easily be achieved byinstallation of a two or three way valve intothe HRC control supply line to direct thepilot supply back to the reservoir at lowpressure. This will prevent unintentionaloperation of the controls on entering orleaving the machine.

DescriptionThe ACX2 pilot pressure supply unit isused to feed one or more Vickers HRCor other similar hydraulic remotecontrols. It maintains pilot pressurewithin pre-set limits when inlet pressurevaries above the minimum set reducedpressure.

Two parallel-connected inlet ports withintegral shuttle valve allow the supply tobe drawn from one or two sources.

ACX2 supply units are available with orwithout an integral nitrogen-loadedaccumulator, the latter also allowingoperation for short durations when thevehicle engine is idle.

Installation and start-up, accumulator models These are shipped with accumulator pre-charged withnitrogen to a specified pressure. The pre-charge should notnormally need initial re-adjustment unless a differentpre-charge pressure is needed for the application. Ifnecessary, users can alter the pre-charge pressure bytemporarily fitting an appropriate charging device jointly to thegas port and a nitrogen bottle, then carefully adjusting thepre-charge within appropriate limits.

If the accumulator is empty of oil when starting, a backpressure of at least 8 bar (116 psi) is needed at outlet PV toassist filling with oil. This is usually attained by running theengine-driven pump(s) at high speed for 10 to 15 seconds.
