Bermad Model 105 - Basic Hydraulic Valve

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.

Bermad Hydraulic Valve Model 105 - Operation

Line Pressure [1] is applied to the Control Chamber [2] through the Manual Selector [3]. This creates superior closing force that moves the Diaphragm Assembly [4] 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.

Typical Applications

  • Computerized Irrigation Systems
  • Distribution Centers
  • Low Supplied Pressure Irrigation Systems
  • Energy Saving Irrigation Systems
