1. Remove the relief valve assembly as outlined on page 5.
2. 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.
3. 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 counterclockwise against
the cage. The seat, spring cage, spring and disc assembly
are now individual components.
4. The disc assembly may now be cleaned and reassembled
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 silicon grease. For more
information refer to repair parts price list PL-RP-BPD.
5. Reassemble 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. Replace relief valve assembly.
NOTE: No special tools required to service Series 009 2
