User manual BENDIX RV-1 PRESSURE REDUCING VALVE

[. . . ] When the force of the spring above the piston overcomes that of the air pressure below the piston, the exhaust valve is seated, and the pressure in the delivery line is the same as the setting of the pressure reducing valve. Note: The RV-1TM valve should be used in light duty applications where the supply and delivery pressure is stable and constant. Please consult Bendix Engineering with specific application requirements. OPERATION The pressure setting of the pressure reducing valve is determined by the setting of the adjusting cap, which exerts a force on the spring on top of the piston. [. . . ] The lock nut should be tightened after readjustment, while holding the adjustment cap stationary. If the RV-1TM 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-1TM valve should be inspected every 6 months or 1500 operating hours, whichever comes first, for proper operation. Should the RV-1TM valve not meet the elements of the operational tests noted in this document, further investigation and service of the valve may be required. TM WARNING!PLEASE READ AND FOLLOW THESE INSTRUCTIONS TO AVOID PERSONAL INJURY OR DEATH: When working on or around a vehicle, the following general precautions should be observed at all times. Park the vehicle on a level surface, apply the parking brakes, and always block the wheels. 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. 3. Do not attempt to install, remove, disassemble or assemble a component until you have read and thoroughly understand the recommended procedures. Use only the proper tools and observe all precautions pertaining to use of those tools. If the work is being performed on the vehicle's air brake system, or any auxiliary pressurized air systems, make certain to drain the air pressure from all reservoirs before beginning ANY work on the vehicle. If the vehicle is equipped with an AD-IS® air dryer system or a dryer reservoir module, be sure to drain the purge reservoir. Following the vehicle manufacturer's recommended procedures, deactivate the electrical system in a manner that safely removes all electrical power from the vehicle. [. . . ] Carefully insert the inlet/exhaust valve guide into small opening in piston. Using needle-nose pliers, grab end of inlet/exhaust valve spring and twist the end into the groove of valve body. Adjust and test valve as outlined in "Operating and Leakage Tests" section. CLEANING AND INSPECTION Wash all metal and plastic parts in mineral spirits. [. . . ]
