of the BOMCO JA-3 Shear Pin Mud Pump Relief Valve. is recommended that a suction pressure relief valve be used in the suction line to prevent damage to either pump in the event of a high pressure surge occurring in the line.
JA-3 Shear pin relief valve can be connected in two ways, one is threaded connection, and the second is flange connection. It is an insurance of mud pump, before the pump working, determines the rated pressure according to the cylinder and piston specification, the safety valve cover off the shear pin on the clipboard into the pin hole. If the pump head pressure exceeds the rated pressure, shear pin will be cut and mud from the side of the vent valve, play a protective role.
Safety valve is used as a mud pump fluid end accessory in the oil drilling industry.
The safety valve serves to guarantee smooth operation of a mud pump within rated working pressure range.
The safety valve offers easy reset, flexible operation, small bearing area, and high universality.
Shear pin safety valve is used at the discharge part of the mud pump.JA-3 shear pin safety valve changes the discharging pressure by changing the position of the shear pin ,which is operation easy and work reliable.
JA-3 Shear Relief Valve, also named shear pin safety valve is used at the discharge part of the mud pump.
JA-3 shear pin safety valve changes the discharging pressure by changing the position of the shear pin ,which is operation easy and work reliable.

1. Opening and shutting neatly.
2. Piston's bearing pressure area is small.
3. To reposition simply.
4. Safety Valve may use for multifold mud pumps.
5. flange / screw thread connection
6. Max pressure:35Mpa
It is recommended that the valve be located on the suction manifold of the pump, but may be located elsewhere on the suction line at the customer’s discretion.
The outlet line from the relief valve should gradually slope down to the tank level, and should be supported to prevent any dips or low spots where mud could collect, harden and potentially block flow.
The relief valve should be set to 50% greater than the normal operating pressure (70 psi for normal operations, but this value may vary depending on the specifics of the job).
