Model 105 is a hydraulically self-operated, diaphragm-actuated valve, which uses the hydraulic force of the existing line pressure, to open and close (an external pressure source, water or air, may be used for closing). Recommended for many On\Off and regulating applications, Model 105 is particularly suitable for agricultural irrigation heads, and filter stations.
The BERMAD Hydraulic Control Valve is a hydraulically operated, diaphragm actuated control valve that opens and shuts in response to a pressure command.
Hydraulic Control Valve
Engineered Plastic Valve with Industrial Grade Design
Yflow ‘Y’ Valve Body with “Look Through” Design
Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
Line Pressure  is applied to the Control Chamber  through the Manual Selector . This creates superior closing force that moves the Diaphragm Assembly  toward a closed position. The discharge of pressure from the control chamber causes the line pressure acting on the diaphragm assembly to move the valve to an open position.
 BERMAD Model IR-105-Z opens upon local manual command.
