Flow Control and Pressure Reducing Valve

The BERMAD Flow Control and Pressure Reducing Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. It controls system demand to a preset maximum flow rate; it reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to an electric signal from an irrigation computer.

Features and Benefits

Hydraulic Flow & Pressure Control with Solenoid Control

  • Limits fill-up rate and consumer over-demand
  • Protects downstream systems
  • Electrically controlled On/Off

Advanced Globe Hydro-Efficient Design

  • Unobstructed flow path
  • Single moving part
  • High flow capacity

Fully Supported & Balanced Diaphragm

  • Requires low actuation pressure
  • Excellent low-flow regulation performance
  • Prevents diaphragm distortion

Hydraulic Flow Sensor (upstream installation)

  • No Moving parts
  • No need for flow straightening

Simple In-Line Inspection and Service
