1. Remove the retainer from the body bore. The check valve

modules can now be removed from the valve by hand or

with a screwdriver. Note: The seats and springs of the first

and second check modules are not interchangeable. The

heavier spring and smaller diameter seat belong with the first

check module.

2. The check seats are attached to the cage with a bayonet

type locking arrangement. Holding the cage in one hand,

push the seat inward and rotate clockwise against the cage.

The seat, spring cage, spring and disc assembly are now in-

dividual components.

Note:

⁄4" M2 modules snap apart.

3. The disc assembly may now be cleaned and re-assembled

or, depending on its condition, may be discarded and

replaced with a new assembly from the repair kit. O-rings

should be cleaned or replaced as necessary and lightly

greased with the FDA approved grease. Refer to parts price

list, PL-RP-BPD for more information.

4. Re-assemble the check valve modules. Check modules are

installed in the valve body with the seat facing the valve inlet.

The modules must be securely in place before the retainer

can be replaced. On the

⁄4" size retainer may have to be tilt-

ed slightly into place. Replace relief valve assembly.
