QUICK PRESSURE RELIEF VALVE
• The 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 repeatability responds to system pressure rise by fully opening. It provides smooth drip tight closing.
• Optional size:1.5″(Dn40),2″(Dn50),2.5″(Dn65),3″ (Dn80),4″(Dn100),5″(Dn125),6″(Dn150)
• Connection method: internal thread/flange
• Motor valve voltage: AC (DC)24V /12-24V DC pulse
