Hydraulic Control Valve with Independent Lift Check Model 700-2S Integral check valve “Y” or angle, wide body Easy addition of features In-line serviceable Drip tight sealing Simple retrofit The Bermad Model 700-2S Hydraulic Control Valve with Independent Lift Check is a hydraulically operated, diaphragm actuated control valve with an integral, lift type, spring loaded non return valve that opens to allow flow in the required direction and smoothly closes drip tight to prevent back flow. Typical Applications ■ Pump control valves ■ One-way level control valve ■ One-way zone backup ■ Return flow prevention Line pressure applied to the upper control chamber of the valve creates a superior force that moves the valve to the closed position and provides drip tight sealing. Discharging the pressure from the upper control chamber to atmosphere or some other lower pressure zone, causes the line pressure acting on the seal disk to move the valve to the open position The independent seal disc assembly closes as soon as differential pressure force across the valve is lower than the spring force, preventing reverse flow through the valve regardless of control chamber pressure and the position of the diaphragm.
