disassembly. (See Metal Seat Valves disassembly
instructions, point (b) on page 16.)
8. The valve is now ready for setting. After the set
pressure has been adjusted, tighten the adjusting screw
locknut (13). Install the cap (18) and cap gasket (17), or
lifting gear, on the valve after applying a small amount
of non-copper based thread lubricant to the gasket seal
surfaces, as well as to the cap and bonnet threads.

1. All bases shall be lapped flat enough to remove nicks
and burrs.
2. Bearing surfaces should be ground together using a
320 grit lapping compound (see Table 17), clean all
parts before assembly. These surfaces are:
a. The disc holder-spindle pocket and spindle spherical
nose radius.
b. The lower spring washer and spindle spring washer
radius.
c. The upper spring washer and adjusting screw
spherical radius.
3. Carefully insert a new O-ring seat seal (37) into the
disc holder (4). Make sure the O-ring is the right size,
material and hardness for the application. Refer to the

5. Place the disc holder assembly onto the base (1)
339
and place the guide (5) onto base. The guide seating
542
surfaces should be free of any nicks or scratches.

6. Lubricate the spindle nose with a small amount of non-
1356
copper based thread lubricant and insert the spindle (9)
407
into the disc holder spindle pocket.

7. Apply a small amount of non-copper based thread
407
lubricant on the bearing surface of the lower spring
407
washer (10) and slip it over the spindle (9). Install the
1017
spring (11) and upper spring washer (10).

8. The guide bonnet seating surfaces should be free
1017
of any nicks or scratches, with a 63 RMS finish
1017
(maximum). Apply non-copper based thread lubricant
2034
to the bonnet and base threads and guide seating
2034
surfaces. Install the bonnet (6) on the base (1) using
torque from Base Torque Specifications (see Table 10).
Before tightening the bonnet completely, adjust the
position of the guide (5) so that one of the holes in the
guide is in line with the discharge of the valve. Tighten
the bonnet using sufficient torque from Base Torque
Specification (see Table 10).
9. Thread the adjusting screw locknut (13) onto the
adjusting screw (12). Apply a small amount of non-
copper based thread lubricant to the tip of the adjusting
screw. Install the adjusting screw in the bonnet, rotating
the number of times required to compress the spring
slightly. Use pliers to hold the spindle (9) in position
and prevent galling. Adjust the adjusting screw to the
measurement recorded during disassembly. (See O-ring
seat seal valves (DA) disassembly instructions, point (b)
on page 20.)
10. The valve is now ready for setting. After the valve set
pressure has been adjusted, tighten the adjusting screw
locknut (13). Install the cap gasket (17) and cap (18), or
lifting gear, on the valve after applying a small amount
of non-copper based thread lubricant to the gasket seal
surfaces, as well as to the cap and bonnet threads.
