General applicationFood and beverage processing, dry bulkconveying, paper mills, slurry handling etc. Inthe highly specialized field of pressure reliefdevices, no manufacturer can match thediversified products and experience ofAnderson Greenwood. With more designsthan any other worldwide manufacturer,Anderson Greenwood’s product technologysolves applications from the most severeproblem to very basic service conditions.

Specifications• Durable but replaceable Teflon® or PEEK

seat in main valve, located on the piston totake the wear. A totally captive seat designeliminates seat extrusion at elevatedtemperatures.

• Teflon®/PEEK seals throughout main valveand pilot for optimum chemical resistance,such as needed for various chemicals inboiler feedwater.

• Single point set pressure adjustment.

• Field replaceable main valve nozzle.

• Non-flowing, all plastic seat/seals, pilot.

• Lifting Lever and Pilot Supply Filter arestandard accessories.

Technical dataSizes: 1" x 2" to 8" x 10"

Orifices: 0.307 to 38.96 in2[1.981 to 251.3 cm2]

Inlet Ratings: ANSI Class 150 to 2500

Max Temperature: 515°F [268°C]

Set Pressures: 15 to 6170 psig [1.03 to 454.4 barg]

Code: ASME I

Features and Benefits• Reduced product loss and pollution:

Soft seats for premium tightness before and after relief cycles.

• All plastic soft goods: There are noelastomer seats or seals providing forchemical compatibility with corrosioninhibitors which may be found in feedwater service.

• Increased system output: Because of totalvalve tightness to at least 96 percent of setpressure, the system can be operated closerto set pressure without valve leakage. Theresult is greater system productioncapability.

• Reduced maintenance costs: Resilientseats greatly extend service life. Costly andtime consuming metal seat lapping isunnecessary.

• Balanced design: Proper valve operationand lift are unaffected by back pressure.Costly and fragile metal bellows are notrequired. The Series 5100 pilot is exhaustedto the outlet of the main valve with no effecton its set pressure.

• ASME Section I Stamp: Certified National Board capacities for steam andwater per Code Case 2446 assures the userof independent third party flow rateverification.

• Reduced noise:Modulating actionminimizes flow and resultant noise duringnormal system upset reducing noiseabatement costs.

• Non-flowing pilot:Minimizes entrance of dirt and debris in the pilot. Due to lowvelocities within the pilot and supply tubing,most particles will drop out upstream of thepilot inlet screen.

• Ease of Adjustment: Single adjustment for set pressure allows for accurate anddependable testing.

• Rugged pilot mounting: Rigid, low profilebracket mounting protects against vibrationand careless handling.

Anderson Greenwood has developed therevolutionary Series 5100 specifically toserve Economizer applications requiringpressure relief under the stringentrequirements of ASME Section I and CodeCase 2446. This unique and challengingapplication requires premium performanceon a valve that must have ASME Section Icertified capacities for both steam andwater.

A modulating pilot operated pressure relief valve would be the ideal solution tothis difficult application. Since the ASMESection I valve on an Economizerhistorically was certified only on steam, the valve would chatter when exposed toeither water or flashing water service whichis the typical real world scenario. CodeCase 2446 was developed and approved tocorrect this situation. Instead of openingquickly (as occurs with a spring-loadedvalve or a snap-acting pilot operated valve),a modulating pilot operated valve wouldonly open proportional to the specificoverpressure need, thereby eliminatingvalve chatter.

Anderson Greenwood Series 5100 was the first and is the ONLY non-flowing,modulating pilot operated pressure reliefvalve that is certified under ASME Section I.The Series 5100 is a unique soft seatedpressure relief valve that requires noelastomer seats or seals. All plastic softgoods trim materials provide an economicalway to handle high temperatures andaggressive lading fluids. This designprovides an alternative to the traditionalmetal seated direct acting pressure reliefvalves used in these installations.

The result is a modulating, soft-seated, pilot operated valve offering premiumtightness with the ability to handle relievingtemperatures to 515°F [268°C] and a setpressure range of 15 to 6250 psig [1.03 to430.9 barg].

The Series 5100 pilot is the latesttechnology from Anderson Greenwood. It is the first all plastic soft seat and sealedvalve that operates as a non-flowingmodulating pilot. There are no pilotcomponent changes required to handle

service conditions changing to and fromsteam and water.

The soft seat in the Series 5100 main valveis more resistant to particulate damagethan a metal seat, has a longer service life,and can be quickly replaced while the valvebody remains installed in the line.

Its unique design enables the main valve tobe tight at pressures up to set point. Afterrelieving and reseating, it stays bubble-tight, cycle after cycle.

Operation

95% Set PressureMinimum

In normal operation, the system pressureacts on the area contained by the mainvalve seat at the bottom of the free-floating differential area piston and onthe top of the piston. Since the top of thepiston is larger than the bottom (seatarea), there is a large downward net forceholding the piston closed. Under staticconditions, the seating force increases asthe system pressure increases andapproaches set point.

Just prior to set pressure the pilot opensand partially depressurizes the dome.This reduces the force on the top of the

piston. The set pressure is the pointwhere the upward force on the mainvalve seat area can overcome thereduced downwardloading. This causesthe piston to lift, resulting in modulatedflow through the main valve. As the mainvalve is relieving the flow through thepilot stops.

When the relief demand has beensatisfied, the pilot closes, full systempressure is diverted to the dome, and thepiston moves downward, closing themain valve.

A patented, pressure responsive piston drag system in the larger Series 5100valves eliminates resonant chatter andthe severe valve and/or piping damage itcan cause. The wedge ring creates apressure-actuated sliding friction forcebetween the piston and liner, preventingresonant chatter.

Notes:1. There are no recognized API “full-bore”orifice areas. These effective areas arespecific to Anderson Greenwood.

2. Set pressure range 15 - 6250 psi
