User manual BENDIX RV-3 PRESSURE REDUCING VALVE

[. . . ] The RV-3TM valve has one supply port and one delivery port. A single pipe plug is installed in the control port and should remain in place for most applications of the RV-3TM valve. A rubber exhaust diaphragm is installed in the end of the valve opposite the supply port. Two . 28" (7. 1mm) mounting holes are cast into the valve body. OPERATION The spring force exerted on the piston determines the delivery pressure of the valve. [. . . ] LEAKAGE With supply pressure at the level recommended by the vehicle manufacturer, apply a soap solution to the 1/8" N. P. T. plug, around the supply port cap nut and to the exhaust port. Leakage should not exceed 100 SCCM or a 1" diameter bubble in 5 seconds. If leakage is excessive, the valve should be replaced and the operating and leakage tests performed at the time of replacement. Proceed to the "Removal and Installation" instructions. This concludes the operation and leakage tests and the test gauges should be removed. 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. 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-ISTM air dryer system or a dryer reservoir module, be sure to drain the purge reservoir. 5. Following the vehicle manufacturer's recommended procedures, deactivate the electrical system in a manner that safely removes all electrical power from the vehicle. Never exceed manufacturer's recommended pressures. Never connect or disconnect a hose or line containing pressure; it may whip. Never remove a component or plug unless you are certain all system pressure has been depleted. Use only genuine Bendix ® replacement parts, components and kits. [. . . ] 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. [. . . ]
