Hydraulic Control Valve

The BERMAD Normally Closed, Hydraulic Control Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

Features and Benefits

  • Hydraulically Controlled, Normally Closed Valve
    • Line pressure driven
    • Closes upon control failure
    • Amplifies and relays weak remote command
    • Hydraulically controlled On/Off
  • Advanced Globe Hydro-Efficient Design
    • Unobstructed flow path
    • Single moving part
    • High flow capacity
  • Fully Supported & Balanced Diaphragm
    • Requires low opening and actuation pressure
    • Progressively restrains valve closing
    • Prevents diaphragm distortion
  • User-Friendly Design
    • Simple in-line inspection
    • Easy addition of control features

Typical Applications

  • Computerized Irrigation Systems
  • Remote and/or Elevated Systems
  • Large Diameter Distribution Centers
  • Irrigation Machines
  • Low Supplied Pressure Irrigation Systems
