Quick Pressure Relief Valve IR-WW-73Q

The Model 73Q Quick Pressure Relief Valve is a hydraulically operated, diaphragm actuated control valve that relieves excessive system pressure when this pressure rises above the pre-set value. It
immediately, accurately, and with high repeat-ability responds to system pressure rise by fully opening. The Model 73Q provides smooth drip tight closing.
