200-PV-9 Pressure / Vacuum Relief Cap for Mobile Fuel Tanks
ENSURE THAT THE CAP IS KEPT FREE OF DEBRIS, RAGS,
DIRT, SNOW AND ICE. FOR CORRECT OPERATION THIS CAP
REQUIRES A CLEAR AIR FLOW PATH FROM THE TANK TO
ATMOSPHERE. BLOCKAGE OF THIS FLOW PATH WILL
PREVENT THE CAP FROM VENTING AND MAY RESULT IN THE
TANK BURSTING OR COLLAPSING.
Immediately remove from service any pressure / vacuum
relief cap that is not performing satisfactorily.
Dixon Bayco pressure / vacuum relief caps are tested at the factory
and are in proper working condition when shipped. Pressure /
vacuum relief caps are designed to be tough and to provide long
service with reasonable care and handling Dixon Bayco pressure /
vacuum relief caps should be routinely inspected to ensure correct
operation and particularly to ensure that the relieving components are
free to move and that the airflow path is unblocked.
Disassembly
Prior to disassembly it is recommended that the cap assembly be
removed from the tank to a clean area.
ENSURE THAT THE CAP (3) IS SECURED, BY CLAMPING
OR SIMILAR, TO THE VALVE BODY (1) BEFORE ATTEMPTING
TO REMOVE THE THREE SCREWS (5). FAILURE TO DO SO MAY
RESULT IN SERIOUS INJURY.
1. With the cap (3) firmly secured, unscrew the three countersunk
screws (5) and carefully release the clamp, or other arrangement,
securing the cap (3) to the valve body (1). Remove the cap (3),
spring (6) and screws (5) to a clean safe place.
2. Remove the valve plate (2) by inverting the valve body (1) and
lightly tapping.
Do not attempt to remove the check valve (7) from the valve
plate (2). The check valve is permanently bonded to the valve
plate to ensure a leak tight seal.
Inspect the valve plate (2), valve body (1) and O-ring (4) for damage
or contamination. If necessary the O-ring and sealing surfaces may
be cleaned using warm water to remove any build up.
