around the valve stem. Avoid using a cleaning solu-

tion as it may damage the rubber seals used in the 

valve.

7.

If the valve bonnet assembly is in good condition and is 

not replaced, replace the bonnet seal. Do not reuse the 

old bonnet seal. See “Replacement Parts:” on page 3 for 

the seal number.

8.

Coat seals with grease provided and position in valve 

body/bonnet assembly.

9.

Carefully seat the bonnet assembly on the valve body. 

Be sure the seals are in their proper position. On those 

valves with a spring below the disc, be sure the spring is 

centered in the indentation on the inside of the valve 

body.

10.

After positioning the bonnet assembly, replace the 

screws removed earlier. 

NOTE: When replacing the bonnet assembly on the 4-

inch valve, draw it evenly into the valve body. 

Finger-tighten the eight bolts. Draw the bonnet 

assembly into the valve by tightening, in order, 

bolts 1, 5, 7 and 3 (two turns each). See Fig. 3. 

Repeat until the bonnet assembly is seated. 

Tighten the remaining bolts. Torque the bolts as 

follows:

11.

Remount the actuator on the bonnet assembly. Tighten 

the two set screws (50-60 inch pounds).

12.

Replace the damper crank arm assembly.

13.

Re-attach the wires removed from the actuator terminals 

and turn on the electrical power.

14.

With the gas still off, cycle the actuator to check for 

proper mechanical operation.

CAUTION

Be sure to perform a bonnet seal and seat leak 

check after installation.

Be sure to read and follow all instructions that come 

with the actuators, valves, seal and bonnet kits.

Valve Bonnet Replacement

The entire valve bonnet can be replaced without removing the 

valve body from the gas line. Do not disassemble the valve 

bonnet assembly because the valve seat is not replaceable.

For part numbers, refer to Replacement Parts in the 

Specifications section. Complete instructions for replacing the 

bonnet assembly are included with the replacement part.

Seal Assembly Replacement (Fig. 6)

When removing the bonnet to inspect and clean the valve, 

install new seal assemblies (see Replacement Parts in the 

Specification section). Coat the new seals with the grease 

provided and insert them in the valve body as shown in Fig. 6.

Fig. 6. Proper positions of valve

and bonnet seals in V5097 Valves.

Failure to properly position and seat the seals in the valve body 

can result in a hazardous gas leak. 

After the new bonnet assembly is installed or the bonnet is 

removed for any reason, check for gas leakage around the 

bonnet seal. Turn on the gas at the manual valve. Paint the 

seal area with a rich soap and water solution. Bubbles indicate 

a gas leak. If a leak is detected, check that the bonnet screws 

are tight. If necessary, turn off the gas again and remove the 

bonnet to make sure the seals are properly seated.
