1. Maximum inlet pressures depend upon body materials and temperatures Refer to the nameplate for the maximum inlet pressure of the relief valve or backpressure regulator The relief valve or backpressure regulator should be inspected for damage after any overpressure condition Fisher relief valve or backpressure regulators are NOT ASME safety relief valves Startup The relief valve or backpressure regulator is factory set at approximately the midpoint of the spring range or the pressure requested so an initial adjustment may be required to give the desired results With proper installation completed and relief valves properly adjusted slowly open the upstream and downstream shutoff valves if applicable Adjustment To change the control pressure remove the closing cap or loosen the locknut and turn the adjusting screw clockwise to increase control pressure or counterclockwise to decrease pressure Monitor the inlet pressure with a test gauge during the adjustment Replace the closing cap or tighten the locknut to maintain the desired setting Taking Out of Service Shutdown To avoid personal injury resulting from sudden release of pressure isolate the relief valve or backpressure regulator from all pressure before attempting disassembly 24 35A3174 A A2812 Parts List Type 63EG Main Valve Key Description 1 Main Valve Body 2 Body Flange 3 Cap Screw 3 Stud Bolt 4 Gasket 9 Spring 11 Cage 12 Port Sea2.
