6. Thoroughly clean the seat ring (key 2) threads and the mating threads in the valve body (key 1).
7. Apply anti-seize lubricant to the threads of the seat ring and its mating threads in the valve body.
8. Screw the seat ring into the valve body. Use a 1-3/16 inch socket wrench to tighten the seat ring to 170 NSm(125
lbfSft). Remove all excess lubricant after tightening.
9. LubricatethebonnetO-ring(key4)withlithiumgreaseandinstallonthebonnet.
10. Apply anti-seize lubricant to the threads on the valve body and bonnet nut (key 5) and the contact surfaces of the
bonnet and bonnet nut flange. Install the bonnet and actuator assembly onto the valve body. Tighten the bonnet
nut until the nut stops turning. A few hammer blows will be required to ensure that the assembly is tight.
11. Pressurize the actuator to a maximum of 2.41 bar (35 psi) to stroke the valve to m id travel.
12. Loosen the hex socket head cap screws (key 15) and remove the flow adjuster (keys 13 and 14).
13. Relieve pressure to the actuator to fully close the valve.
14. Make sure the valve is fully seated and install the flow adjustor (keys 13 and 14) and hex socket head cap screws
(key 15).
15. Set the desired flow rate position according to figure 2.
16. Tighten the hex socket head cap screws to 3 NSm(26lbfSin).

1. Ensure the threads of the valve stem (key 16) and valve plug (key 3) are clean and free of debris.
2. Make sure the Belleville springs (key 9) are properly installed on the valve stem, as shown in figure 3.
3. Install the valve plug o n the stem and insert a new pin (key 43).
4. Lubricate the threads of the packing retainer with anti-seize and install into the bonnet using a 1-1/8 inch wrench.
Make sure the Belleville springs (key 9) are completely enclosed by the packing retainer as shown in figure 4.
5. Torque the packing retainer to 81 NSm(60lbfSft). The packing retainer has been installed correctly when a metal to
metal contact has been made between the packing retainer end and the bonnet (key 7). The packing retainer
threads should be completelyenclosedbythebonnet.
6. Thoroughly clean the seat ring (key 2) threads and the mating threads in the valve body (key 1).
7. Apply anti-seize lubricant to the threads of the seat ring and its mating threads in the valve body.
8. Screw the seat ring into the valve body. Use a 1-3/16 inch socket wrench to tighten the seat ring to 170 NSm(125
lbfSft). Remove all excess lubricant after tightening.
