The BERMAD Hydraulic Control Valve is a hydraulically operated, diaphragm actuated control valve that opens and shuts in response to a local or remote pressure command.
Operations
Hydraulic Command 1 is applied to the Control Chamber 2 through the Manual Selector 3 . This creates superior closing force that moves the Diaphragm Assembly 4 to a closed position. Discharging of pressure from the control chamber, by turning the manual selector, causes the line pressure acting on the lower side of the diaphragm assembly to ove the valve to an open position
