PRESSURE RELIEF VALVE

DANGER !

Before opening any Viking pump liquid chamber (pumping chamber, reservoir, etc.) Be sure:

1.That any pressure in the chamber has been completely vented through the suction or discharge lines or other appropriateopeningsorconnections. (See detailed procedure for venting the pumps, pages 4, 5 and 6).

2.That the driving means (motor, turbine, engine, etc.) has been “locked out” or made otherwise non- operational so that it cannot be inadvertently started while work is being done on the pump.

3.That you know what liquid the pump has been handling and the precautions necessary to safely handle the liquid. Obtain a material safety data sheet (MSDS) for the liquid to be sure these precautions are understood.

Failure to follow above listed precautionary measures may result in serious injury or death.

ASSEMBLY: RELIEF VALVE

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. Refer to Figure 3, page 2.

PRESSURE ADJUSTMENT

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 adjustment operation.

3.Turn adjusting screw in to increase pressure and out to decrease pressure.

4.With discharge line closed at a point beyond pressure gauge, gauge will show maximum pressure valve will allow while pump is in operation.

IMPORTANT

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.

DISASSEMBLY: RELIEF VALVE

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 23.

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 as necessary.

DANGER !

Before starting pump, be sure all drive equipment guards are in place.

Failure to properly mount guards may result in serious injury or death.
