The structure of JA-3 shear relief valve is showed above. When the pressure is more than the rated data, the piston raises, jacks up the shear board to break off the shear pin so as to empty the sap flow promptly.
JA-3 safety valve is an integral part of the protection mud pump pressure relief system. The safety valve ensures that the mud pump is operating normally within the rated operating pressure range.
Types of Safety Valve:
It can be divided into high-pressure JA-3H safety valve and JA-3 safety valve, according to different pressure. JA-3H is used for high-pressure mud pump.
According to different connections, it can be divided into safety valve with flange connection, and safety valve with thread connection.
