1.0 General valve description & start up

1.1 OperationThe AGCO Series 5000 valve is designed for modulating action. The main valve will open at nameplate set, but only an amount proportional to the relieving capacity required. As process pressure increases, the valve will open more and be in full lift at 110% of set.The main valve uses the principle of pressurizing the larger area of a differential area piston with line pressure to hold the piston closed up to set pressure. At set pressure, the pilot relieves, depressurizing the volume on the larger area side of the piston. Line pressure acting on the smaller area side causes it to lift, permitting discharge from the main valve. As capacity relief of the system is satisfied, system pressure will begin to decrease. When it does, the pilot will actuate and direct system pressure to the larger area side of the main valve piston to close it.The set pressure range is 15 psig to 6170 psig for air, liquid and gas. For steam the set pressure range is limited to a temperature 515°F.

1.2 OperationEither or both inlet and outlet may be standard ANSI flanges or API flanges and are to be installed in accordance with accepted piping practices.

1.3 Start-upThere must be pressure at the valve inlet or at the pilot inlet/sense port for valves with remote sense to establish a differential force across the piston and “load” it in the closed position. Pressure must pass through the pilot and exert force on the top of the piston. On normal plant start-up the valve will close itself as pressure increases.Block valves are often used under safety valves to isolate them when maintenance is required. When putting the safety valve in service be sure the block valve is fully opened. If the block valve is opened after system start-up, the safety valve may briefly vent before the volume on the larger area side of the piston gets pressurized to close the main valve seat disk.

1.4 MaintenanceAnderson Greenwood Crosby recommended main valve and pilot maintenance procedures including pilot set pressure adjustment and valve assembly testing are described in the following paragraphs. Following these procedures in a regular pressure relief valve maintenance program appropriate for the specific operating conditions will insure satisfactory valve performance and provide optimum service life.Should the pressure/media requirements of a pilot operated pressure relief valve be outside the capabilities of the repair facility, contact Anderson Greenwood Crosby for specific instructions before starting any maintenance activity.This manual is provided as a general guide for the maintenance of the safety valves described herein. It does not include procedures covering all valve configurations and variations manufactured by Anderson Greenwood Crosby. The user is advised to contact Anderson Greenwood Crosby or one of our authorized representatives for assistance with valve configurations

2.3 Assembly2.3.1 Nozzle and nozzle seal installation1. Place nozzle seal and nozzle in body.2. Place nozzle retainer over nozzle and thread into body until it stops on nozzle shoulder. Do not

lubricate nozzle retainer threads or mating body threads.3. Repeat steps 1 through 4 of disassembly procedure to compress nozzle seal. Thread nozzle

retainer into body as seal is compressed to keep nozzle retainer from binding against piston.4. Use a punch or bar with a light hammer and tap on the nozzle retainer teeth to snug the nozzle

retainer threads.5. Loosen cap bolts to remove load from spacer and remove spacer from valve.

Replace seat, piston and liner seal. Apply a light coat of Dow Corning #33 silicone lubricant on all threads after cleaning. Do not use any lubricant on the soft goods.When installing the cap, make sure it is seated squarely into body. Torque cap bolts uniformly so as not to “cock” cap. See Table II for torque values. Such a condition may result in leakage at the liner seal or cause the piston and liner to bind.

2.0 Main valve maintenance

2.1 DisassemblyRefer to Figure 1 for parts description and location.Unscrew the bushing/siphon tube and remove the bushing seal. Remove the cap from the body. Remove the piston and liner. A bolt may be threaded into hole in top of piston to aid in removal. Through holes in seat retainers 2”, 3” & 4” sizes are threaded to assist in disassembly. Remove the soft goods from the piston. If the piston is equipped with a wedge ring, clean and retain it for use during assembly. The dipper tube is swaged in place and no attempt should be made to remove it. Refer to Figure1 for parts description and location. The nozzle and nozzle seal should not be removed unless the nozzle is damaged or the seal is leaking.

2.1.1 Nozzle and nozzle seal disassemblyRefer to Figure 2 for parts description and location.1. Place liner in body and piston, without seat or seat retainer, into liner and on top of nozzle.2. Place appropriate spacer (see Table I) on top of piston and then the cap over the spacer.3. Thread the appropriate number of cap bolts (see Table I) into threaded holes on top of body.

If two bolts are used, they should be 180° apart. When using four bolts, they should be 90° apart.

4. Tighten cap bolts evenly to the torque listed in Table I to compress nozzle seal.5. Use a punch or bar with a light hammer and tap on the nozzle retainer teeth to loosen the

nozzle retainer. Unthread nozzle retainer approximately 1/2 turn.6. Loosen cap bolts to remove load from nozzle. Remove components from main valve.

4.0 Pilot set pressure adjustment

4.1 DefinitionsSet pressure is defined as the supply pressure on increasing pressure at which the dome pressure is 70% of the supply pressure. This corresponds to the first steady stream of liquid from the main valve.Crack pressure is defined as the supply pressure on increasing pressure at which dome pressure reduction first occurs.Reseat pressure is defined as the supply pressure on decreasing pressure at which the dome pressure increases to 75% of supply pressure. The pilot dome pressure may continue to increase after reseat.

4.2 Set pressure, standard pilot 4.2.1 Initial adjustment on air To adjust the set pressure, a test set-up similar to that shown in Figure 5 should be used.

The test media should be air. The adjustment screw should be turned IN most of the way. Increase the supply pressure to nameplate setting and slowly back out the adjustment screw until flow through the pilot exhaust begins. Continue to slowly back out the adjustment screw until dome pressure is 70% of the supply pressure and the supply pressure meets the required set pressure tolerance of paragraph 4.4. After adjustment is completed, securely tighten the jam nut.

To determine reseat pressure, shut off the air supply and use the accumulator vent valve to slowly reduce the supply pressure until the dome pressure is 75% of supply pressure.

Close the shut-off valve and slowly open the bleed valve. When the dome pressure gauge reading is zero, the pilot may be removed from the test set-up.

4.2.2 Liquid service pilot Note: An initial set pressure adjustment may be made with air as the supply pressure media using

a test set-up similar to that shown in Figure 5 and following the procedure described in paragraph 4.2.1 above. This initial set pressure may be lower than the set pressure observed when the pilot is tested on liquid.

To adjust the set pressure, a test set-up similar to that shown in Figure 6 should be used. The test media should be water. Some air volume must be maintained above the water surface in the accumulator. The adjustment screw should be turned IN most of the way except when an initial adjustment was made on air.

Increase the air supply pressure to nameplate setting and slowly back out the adjustment screw until water flow through the pilot exhaust begins. Continue to slowly back out the adjustment screw until dome pressure is 70% of the supply pressure and the supply pressure meets the required set pressure tolerance of paragraph 4.4.

To determine reseat pressure, shut off the air supply and use the accumulator vent valve to slowly reduce supply pressure until the dome pressure is 75% of supply pressure.

Close the shut-off valve in the water line to the pilot inlet port and slowly open the bleed valve. When the dome pressure gauge reading is zero, the pilot may be removed from the test set-up.

The optional indicator assembly shown in Figure 5 may be used for set pressure above 70 psig. If an indicator assembly is used, slowly increase the supply pressure until the indicator pin pulls into the indicator assembly and is approximately flush with the end of the indicator body. The pressure when the pin pulls in is the set pressure. Loosen the jam nut, adjust the adjustment screw, and retighten the jam nut as required to meet the set pressure tolerance of paragraph 4.4.

Shut off the air supply and use the accumulator vent valve to slowly bleed down supply pressure until the indicator pin “pops” out of the indicator assembly (full extension of the pin is approximately 7/16”). The pressure when the pin “pops” out is the reseat pressure.

Close the shut-off valve in the water line to the pilot inlet port and slowly open the bleed valve. When the dome pressure gauge reading is zero, the pilot may be removed from the test set-up.

4.3 Range of adjustmentAll pilots can be adjusted +/- 5% beyond the nameplate setting. If a set pressure change is made that requires a new spring, consult Factory for information contained in spring chart.

4.4 Performance requirementsAll pilots can be adjusted +/- 5% beyond the nameplate setting. If a set pressure change is made that requires a new spring, consult Factory for information contained in spring chart.

5.0 Valve assembly testing

5.1 GeneralThe complete valve assembly should be tested for internal and external leakage and to verify main valve function using a test set-up similar to that shown in Figure 7. The test media should be air.Note: Actuate valve a minimum of two (2) times before testing for pilot seat leakage.

6.0 Soft goods repair kit

See manufacturer.

CAUTION

Do not test liquid service valves using water or other liquid test media. Liquid service valves should be tested using air as the test media in accordance with the procedures described below. Testing fully assembled liquid service valves using air insures that no water or other liquid will remain in the main valve dome after final valve testing.

5.2 High pressure leakage checkApply pressure to the inlet equal to 90% of the set pressure. Check for leakage at the main valve outlet. Using a suitable gas or air leak detector solution, check for leakage at the cap seal and other pressure connections. No leakage shall occur at the valve outlet and no visible leakage shall be detected at the cap seal or other pressure connections in one minute.
