APPLY LUBRICANT / SEALANT

(1)

S = THREAD SEALANT

L = ANTI-SEIZE LUBRICANT

1. Lubricant and sealant must be selected such that they meet the temperature requirements.

Perform the following procedure if O-rings are

leaking or if there is a need to inspect and remove

accumulated dirt, mineral deposit, clogged debris or

sediment buildup inside the restrictor. Key numbers

are referenced in Figure 16.

1. Unscrew the groove valve (key 22) and retainer

(key 23) just enough to loosen them, but do not

completely separate.

2. As shown in Figure 15, push on the retainer

(key 23) to push the groove valve (key 22) out of

the body (key 21), then complete disassembly.

3. Inspect the gaps and small spaces inside

the restrictor. Check and remove any debris,

accumulated dirt, mineral deposit or sediment

buildup that clogs the restrictor.

4. Replace the groove valve O-rings (key 24) if

necessary, being sure to lightly apply lubricant to

the replacement O-rings before installing them in

the groove valve and retainer.

5. Install the groove valve (key 22) into the same

side of the body where the scale appears. Install

the retainer into the opposite side of the body and

tighten until both are secure.

6. When all maintenance is complete, refer to the

Startup and Adjustment section to put the regulator

back into operation.
