QUICK PRESSURE RELIEF VALVE Model 73Q

Hydraulically operated, diaphragm actuated quick pressure relief valve that relieves
excessive system pressure when such pressure rises above a pre-set value.It
responds immediately, accurately, and with high repeatability to a rise in system
pressure by opening fully. It also provides smooth drip tight closing.

either standard oblique (Y) or angle (A) pattern design. They have a full bore
hydrodynamic body providing an unobstructed flow path, with a seat assembly
and double chamber unitized actuator that can be disassembled from the body
