1. IntroductionThe TDA series two-port proportional throttle valves are used to control large flows of oil.

FunctionProportional throttle valves have a three-level structure. The valve poppet is pilot-controlled by a seat-type follower piston. A proportionally adjust-able valve with feedback controls the position of the follower piston. This means that the position of the poppet cannot be influenced by the differ-ential pressure. The flow in the standard version of the valve passes from B to A, which means it is leakage-free from B to A in the closed starting position. In this starting position, the pilot control does not require pilot oil.In combination with the digital amplifier module PCD00A-400 (not explosion-proof) the valve pa-rameters can be stored, changed and duplicated.The type of protection for the valve is: II 2 GD c T 130°C (T4)for use in zones 1, 2, 21 and 22.

The pilot pressure in X-line must be at least 25% (NG16-40) or 45% (NG50-100%) of the pressure in the draining-off line of the cartridge to make sure that the main poppet closes safely without malfunction.

2. Safety instructionsRead the operating instructions thoroughly before installation, commissioning, maintenance, repair and storage, and observe them. Failure to observe the operating instructions may result in damage to the valve or the parts of the system connected to it.In particular, in the case of explosive atmospheres, any failure to observe the operating instructions may result in an explosion.The system operator must make these operating instructions visible and easily accessible to operat-ing and maintenance personnel.Compliance with applicable standards/legal require-ments must be enforced. This particularly applies to plant safety and environmental protection.A list of such standards, etc. appears in the annex by way of example.Before starting commissioning, installation, main-tenance and repair work, the hydraulic system must be depressurised and power must be discon-nected from the electrical installation.In addition, the electrical installation must be secured so that power cannot be restored unexpectedly.The valve may become hot during operation. To avoid risk of burns, do not touch the valve surface.The system operator must monitor the temperature and cool the oil if necessary in order to the keep within the maximum temperatures set out in these operating instructions (see page 6). In this connec-tion, observe the relevant directions in the operat-ing instructions of the supplier (solenoid system).Any leaks occurring at the valve must be rectified immediately.Furthermore the system operator has to ensure that the thickness of a possible dust layer never exceeds the height of 1 mm to prevent a smoulder-ing fire securely.

• Before installation, remove the protective co-ver from the valve ports.

• CheckthatthevalveportsandtheOringsarein the correct position.

• Usefasteningscrewsasindicatedinthecata-logue, property class 12.9 to DIN 912.

Parker can supply the correct screw sets, see the catalogue for order numbers.

• Tightenthescrewsdiagonally,torqueasspeci-fied in the catalogue.

• Anydeficienciesofthevalvemountingsurfacemay result in operating disruptions. Faulty fi-xing and incorrect screw tightening torques may lead to the sudden escape of hydraulic fluid at the ports.

The valve must be connected to the equipotential bonding system of the hydraulic system.

4.3. Electrical connectionObserve operating instructions BA012664 in the annex.

4.4. Operation limitsThe valve may only be deployed with the specified limits of use. The relevant details can be found in the catalogue sheet under "Technical data" and "Characteristic curves" (see pages 6 and 7).

Observe the ambient conditions. Unau-thorised temperatures, shocks, the effects of aggressive chemicals, radiation, unau-thorised electromagnetic emissions may result in disruptions and failures. Observe the limits of operation set out in "Technical data".

Excessive temperatures may cause the so-lenoid to overheat, creating the risk of ex-plosion. To permit adequate heat dissipati-on, the solenoid coil should not be painted.

4.5. Pressure fluidsFor details of valve operation using different pres-sure fluids, see HY11-AL103-M1.

The details given here are provided for in-formation only and do not replace in-house testing under the applicable operating con-ditions. In particular, the details cannot be interpreted as a guarantee of media com-patibility.

For detailed information about pressure fluids, see VDMA sheet 24317 and DIN 51524, 51502. Special sealing materials are supplied depending on the fluid used. Please ask the factory if you are unsure.

The pressure fluid must have an ignition tempera-ture of at least 50 K above the maximum surface temperature of the valve (see EN 13463-5 and IEC 60079-4).



TDA-EE_20 5715-645 UK.indd RH 05.06.12

5. Operating instructions

5.1. Electronic control system

The valve must be operated by a suitable electronic control system.

The appropriate electronic control system can be selected from the catalogue ("Elec-tronics" section).

Please ask the factory. if further guidance is required.

Connecting to an unsuitable electronic con-trol system may result in irreparable dam-age to the valve or the electronic control system.

If you are using the Parker PCD00A-400 digital module, make sure that the mod-ule runs outside the Ex area or inside an electrical cabinet certified for use in the Ex zone.

5.2. Air bleeding of hydraulic system

The hydraulic system must be vented on initial commissioning, after an oil change or after lines or valves are opened. Air in the hydraulic system is highly detrimental to the behaviour of the control system and is therefore undesirable. Air bleeding takes place at the highest point of the pipe network.

Loosen the vent screw slightly, allowing air to escape until oil flows. When the escaping oil no longer contains air bubbles, tighten the screw again. Then work through all functions in succession, in no-load operation with the lowest possible pressure, and with the full consumer range. Finally, vent the system again.

After air bleeding, check the oil level in the tank and top up with oil if necessary.

5.3. Filter

The operation and service life of the valve are highly dependent on the cleanliness of the pressure fluid.

Dirt is the biggest enemy of a hydraulic sys-tem.

Be aware of three important sources of contami-nation:

• impuritiesenteringduringinstallation• impuritiesoccurringduringoperation,abrasion• dirtenteringfromthesurroundingsPressure filters must always be used with propor-tional valves. For actual values, see the data sheet.

Follow the maintenance instructions.

5.4. Flushing

With large central pressurised oil stations in particular, you are recommended to flush the long pipes by short circuiting the pres-sure and return lines.

This prevents the dirt occurring during in-stallation from being carried to the valve.

6. Maintenance

Maintenance procedures may only be car-ried out by specialist personnel. A detailed knowledge is required of how the machine is switched on and off and also of the nec-essary safety measures.

Regular maintenance is essential in prolonging the service life of the systems, and safeguards plant safety and operational availability. The following items must be checked at regular and short intervals:

• Oillevelintank• Max.mediumtemperature• Max.surfacetemperature• Condition of the pressure fluid (sight check,

colour and smell of hydraulic fluid)• Operatingpressures• Preload pressure of pressure vessel (if

present)• Noleaksatanysystemcomponents• Conditionofthefilterelements• Conditionofthehoselines• CleanlinessofcomponentsAfter a certain period of service, the hydraulic fluid must be replaced. The frequency of the change depends on the following circumstances:• Typeandgradeofpressurefluid(ageing)• Filtration• Operatingtemperatureandambientconditions

14



TDA-EE_20 5715-645 UK.indd RH 05.06.12

7. TroubleshootingA systematic approach must always be used in the troubleshooting process. Begin by answering the following questions:• Doesanyonehavepracticalexperienceofsi-

milar faults?• Haveanyofthesettingsbeenchangedinthe

system?Now try to identify the fault using a prioritised list of the most likely causes.• Ifyoususpectthatthe valve is not moving freely, you should flush the valve with clean pressure fluid.

• Asystematicapproachshouldalwaysbead-opted when troubleshooting a hydraulic sys-tem.

The work must only be carried out by specialist personnel because detailed knowledge of the func-tion and structure of the system is required. Always think carefully about changing settings or removing components. Before starting work, check that the system was working correctly before the fault oc-curred.Following any repair, commissioning must be car-ried out as instructed.
