TECHNICAL SERVICE MANUAL
Mark valve and head before disassembly to insure proper
reassembly.
1. Remove valve cap.
2. Measure and record length of extension of adjusting
screw. Refer to “A” on Figure 12 and Figure 13.
3. Loosen locknut and back out adjusting screw until spring
pressure is released.
4. Remove bonnet, spring guide, spring and poppet from
valve body. Clean and inspect all parts for wear or
damage and replace if necessary.
Reverse procedures outlined under Disassembly. If valve
is removed for repairs be sure to replace in same position.
Relief valve adjusting screw cap must always point towards
suction side of pump. If pump rotation is reversed, remove
relief valve and turn end for end.
If a new spring is installed or if pressure setting of pressure
relief valve is to be changed from that which the factory has
set, the following instructions must be carefully followed.
1. Carefully remove valve cap which covers adjusting
screw.
Loosen locknut which locks adjusting screw so pressure
setting will not change during operation of pump.
2. Install a pressure gauge in discharge line for actual
adjusting operation.
3. Turn adjusting screw in to increase pressure and out to
decrease pressure.
4. With discharge line closed at point beyond pressure
gauge, gauge will show maximum pressure valve will
allow while pump is in operation.
In ordering parts for pressure relief valve, always give
model number and serial number of pump as it appears on
nameplate and name of part wanted. When ordering springs,
be sure to give pressure setting desired.
