Pressure Reducing Valve GR-420-bKZ

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand, or varying upstream pressure.

  • Line Pressure Driven
  • Pressure Reducing Servo Pilot Controlled

-Progressive needle valve

-Settable to 0.5 bar; 7 psi

-Very low hysteresis

  • Advanced Globe Hydro-Efficient Design

-Unobstructed flow path

-Single moving part

-High flow capacity

  • Fully Supported & Balanced Diaphragm

-Requires low opening and actuation pressure

-Excellent low flow regulation performances

-Progressively restrains valve closing

-Prevents diaphragm distortion

  • User-Friendly Design

-Easy pressure setting

-Simple in-line inspection and service

Typical Applications

  • Drip-Tape Systems
  • Low Set Pressure Applications
