VALVE ADJUSTMENT
™
If the RV-1
valve does not deliver as described, and leakage
is minimal, the valve can be readjusted as follows.
1. Remove lockwire (if used).
2. Loosen the cap lock nut while holding the adjusting cap
stationary.
3. Turn the adjusting cap clockwise to increase pressure,
counter clockwise to reduce pressure.
4. The lock nut should be tightened after readjustment, while
holding the adjustment cap stationary.
5. Recheck the delivery pressure as described.
6. Reattach the lockwire and replace the seal if used.
If the RV-1
™
valve does not function as described or if
excessive leakage occurs, it is recommended that it be
repaired/replaced with genuine Bendix parts.
PREVENTIVE MAINTENANCE
Important: Review the Bendix Warranty Policy before
performing any intrusive maintenance procedures. A warranty
may be voided if intrusive maintenance is performed during
the warranty period.
No two vehicles operate under identical conditions, as a
result, maintenance intervals may vary. Experience is a
valuable guide in determining the best maintenance interval
for air brake system components. At a minimum, the RV-1
valve should be inspected every 6 months or 1500 operating
hours, whichever comes first, for proper operation. Should
the RV-1
™
valve not meet the elements of the operational
tests noted in this document, further investigation and service
of the valve may be required.
WARNING! PLEASE READ AND FOLLOW

INSTRUCTIONS
PERSONAL INJURY OR DEATH:

parking brakes, and always block the wheels.
Always wear safety glasses.
2. Stop the engine and remove ignition key when
working under or around the vehicle. When
working in the engine compartment, the engine
should be shut off and the ignition key should be
removed. Where circumstances require that the
engine be in operation, EXTREME CAUTION should
be used to prevent personal injury resulting from
contact with moving, rotating, leaking, heated or
electrically charged components.
