1. Before commencing the assembly ensure every part is thoroughly clean. Screw threads should be coated with anti-seizecompound, hydraulic oil may be used to assist the assembly of seals and hydraulic components.

2. Assemble the Seat Seals (6) to the Seats (3). Place the Seats into the seat pockets in the valve Body (1)

3. Slide the Tee section of the Stem (5) into the Tee slot of the Gate (4) and install the Gate down into the Body betweenthe Seats. Body filler Grease may applied to both Gate faces and the Tee slot to provide initial lubrication.

4. Screw Studs (8) into the Body if they have been removed.

5. Apply light grease to the Bonnet Seal (13) and place onto the Body.

6. Place ‘O’ring (14) onto the Bonnet (2) to cover the small leak detection hole. Place ‘O’ring (15) into the groove at theback of the threaded section. If it has been removed replace Grease fitting (10).

14. Place the Cylinder assembly into the Housing (22), install Retaining Ring (35). Invert the housing so that the cylinderassembly comes into contact with the retaining ring (35).15. Place the Upper Retaining Plate (25), Spring (24) and Lower Retaining Plate (23) into the Housing. See Fig 2 forcorrect orientation of the Upper Retaining Plate. Compress the Spring and retain in position with Locking Ring (21) Securethe cylinder assembly in position with 4 off Set Screws (34). (Continue from step 16 page 9)

Actuators will typically be supplied witheither a cover plate or an observation windowon the outside of the cylinder housing. Thisplate or window can be removed to facilitatethe fitting of proximity switches. (see fig 3opposite) Details of electrical connections tothese proximity switches will be suppliedseparately from this publication and willdepend on type supplied and any otheradditional requirements such as terminalboxes that may have been provided at thetime of purchase.Typical set up procedure for these switcheswould be :-• With no hydraulic pressure on theactuator screw the upper switch in until ittouches the upper retaining plate, retract onefull turn then lock into place with the locknut.

• Apply pressure to the actuator so that the cylinder is fully extended, screw the lower switch in until it touches theupper retaining plate, retract one full turn then lock in to place with the lock nut.

16. Fill the Hydraulic Cylinder with oil evacuating all air. Replace Safety Head (36) if fitted and attach the Actuator to theHydraulic System. Pressurise to extend the piston until the Tee slot of the Hydraulic Plug (27) is just below the LowerRetaining Plate (23). Do Not Over Extend The Piston.17. Slide the Tee slot locate on the Hydraulic Plug (27) over the end of the Valve Stem (5). The Stem Locator (26) shouldhold the assembly in position.

18. Release pressure slowly to locate the Housing (22) on to the Support Plate (16). Secure with ‘C’ clamp (20) and 6 offHex Bolts (19).

The valve Gate and Seats may be replaced without dismantling the upper hydraulic components as follows :-

1. If the valve is still in the flowline ensure all pressure has been released and isolate the valve to be maintained by locking /chaining valves upstream and downstream of the subject valve - label them “ CAUTION - DO NOT OPERATE “

Check that all line pressure has been dissipated by using a stinger (part no. 17538) on the grease fitting (10).

2. Detach any hoses or piping connected to the hydraulic cylinder.

3. Unscrew the Nuts (7) from the Studs (8). Lift the bonnet cylinder assembly clear of the Body (1). Caution ! ensure theGate does not damage the top seal face as it is withdrawn from the Body.

4. Pressurise the cylinder to approximately 150 psi to extend the Gate (4) and Stem (5) from the Bonnet. Slide the Gate offthe Stem.

5. Remove the Seats (3) from the Body (1) and remove the Seals (6) from the Seats.

6. Remove the Bonnet Seal (13).

Rebuilding of the Valve from this stage is as follows :-

1. Ensure all parts to be used for the assembly are thoroughly clean and that all old body filler grease has been removedfrom the valve.

2. Insert Seals (6) into Seats (3) and place into Seat Pockets in the Body (1)

3. Place a Bonnet Seal (13) onto the Body.

4 The Cylinder will need to be pressurised to approximately 150 psi to extend the Stem (5) out of the Body. Slide the Teeslot of the Gate (4) on to the Stem (5). Depressurise the Cylinder so that the Gate and Stem retract into the Bonnet.

7. Carefully lower the Bonnet Cylinder assembly down onto the Body ensuring the Gate enters smoothly between the Seats.Replace Nuts (7) to Studs (8)

8. Reconnect hydraulic hoses or piping. Grease the valve through Grease fitting (10).

1. Close the Valve by Venting all hydraulic pressure from the Cylinder. Ensure the Valve has Back Seated by applying astinger part No. 17538 to the grease fitting (10), ALL LINE PRESSURE SHOULD HAVE DISSIPATED.

2. Remove Hex. Bolts (19) and ‘C’ Clamp (20).

3. Pressurise the Cylinder to approximately 150 psi to raise the cylinder from the Support Plate (16). Push the CylinderAssembly in the direction of the Hydraulic Plug Tee Slot and lift from the Valve. Unscrew Shim Adapter (17) and SupportPlate (16)

4. Check the integrity of the Back Seat by reapplying the Stinger to the Grease Fitting (10), there should no pressure at thisport. Unscrew the Packing Gland (12) and retrieve the Seal (9) and Back-up Ring (9A). This operation may be assisted bypumping grease into the seal pocket through the Grease fitting (10).

Rebuild of the valve from this stage is as follows : -

Stem Seal Replacement With The Valve Under Pressure

Gate and Seat Replacement

1. Remove all traces of grease from the seal pocket and inspect the surfaces for damage.

2. Place the Seal (9) followed by Back-up Ring (9A) down over the Stem with the open end containing the spring facingdown.. Install the Packing Gland (12) down over the Stem and screw fully home into the Bonnet. NOTE it will be necessaryto apply the stinger to the Grease fitting (28) during this stage to prevent a hydraulic lock.

3. Replace the Support Plate (16) and lock in place with Shim Adapter (17).

4. Pressurise to extend the piston until the Tee slot of the Hydraulic Plug (27) is just below the Lower Retaining Plate (23)Slide the Tee slot of the Hydraulic Plug (27) on to the Stem (5), the Stem Locator (26) should assist in holding theassembly Central . Depressurise the Cylinder slowly so that the assembly retracts onto the Bonnet.

5. Replace C Clamp (20) and 6 off Hex. Bolts (19).

1. If the valve is still in the flowline ensure all pressure has been released and isolate the valve to be maintained by locking /chaining valves upstream and downstream of the subject valve - label them “ CAUTION - DO NOT OPERATE “

Check that all line pressure has been dissipated by using a stinger (part no. 17538) on the grease fitting (10).

2. Remove Hex. Bolts (19) and ‘C’ Clamp (20).

3. Pressurise the Cylinder to approximately 150 psi to raise the cylinder from the Support Plate (16). Observe the directionof the Tee slot connection between the Stem (5) and the Hydraulic Plug (27). Push the Cylinder Assembly in this directionand lift from the Valve. Unscrew Shim Adapter (17) and Support Plate (16).

4. Unscrew Packing Gland (12) , remove ‘O’rings (18), (15) ,14) and Stem Guide Ring (11).

5. Unscrew Nuts (7) from the Studs (8) and lift the Bonnet (2) from the Body (1). Retrieve Back-up Ring (9A), Seal (9),lower Stem Guide Ring (11) and Grease Fitting (10).

6. Remove the Gate (4) and Stem (5) from the Body (1) then remove the Gate from the Stem.

7. Extract the Seats (3) from the Body and remove Seals (6).

Cylinder Disassembly :-

8. Remove any hydraulic hoses to the Cylinder and Safety Head (36) if fitted. Drain hydraulic oil from the Cylinder.

9. Compress the Spring (24) using tool part No. A30255. Remove the Lower Retaining Ring (21) and the compressiontool.

10. Remove Lower Retaining Plate (23) , Spring (24) and Upper Retaining Plate (25).

11. Remove Upper Retaining Ring (35) and slide the Cylinder Assembly out of the Housing (22). Remove ‘O’ring (33)

12. Slide the Translating Cylinder (29) from the Inner Cylinder (32). Remove Seal (30) and Cylinder Guide Ring (31)

13. Unscrew Hydraulic Plug (27) from the Cylinder (29) and remove ‘O’ring (28).

14. On actuators supplied with rising stem position indicators (page 5 and 6) remove additional components in thefollowing sequence :- Socket Set Screw (42), Stem (41), Stem protector (37), Seals (40), Guide Ring (39) and ExcluderSeal (38). NOTE items (40) and (38) are two part seals.

Visually Inspect :-

• All sealing surfaces for damage

• Screw threads for wear or galling IF IN DOUBT REPLACE

• Gate and Seat surfaces for wear or damage

Complete seal replacement is recommended
