Pressure Reducing and Sustaining Control Valve

The BERMAD Model IR-123-55 is a hydraulic operated, diaphragm actuated control valve that performs three independent functions. It sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to an electric signal.

Features and Benefits

  • Hydraulic Pressure Control with Solenoid Control
    • Protects downstream systems
    • Sustains supply line pressure and controls system fill-up
  • Engineered Plastic Valve with Industrial Grade Design
    • Adaptable on-site to a range of end connection sizes and types
    • Articulated flange connections eliminate mechanical and hydraulic stresses
    • Highly durable, chemical and cavitation resistant
  • hYflow ‘Y’ Valve Body with “Look Through” Design
    • Ultra-high flow capacity - Low pressure loss
  • Unitized Flexible Super Travel (FST) Diaphragm and a Guided Plug
    • Accurate and stable regulation with smooth closing
    • Requires low actuation pressure
    • Prevents diaphragm erosion and distortion
  • User-Friendly Design
    • Easy pressure level setting
    • Simple in-line inspection and service

Typical Applications

  • Computerized Irrigation Systems
  • Pressure Zone Prioritizing
  • Line Fill-up Control
  • Line Emptying Prevention
  • Pressure Reducting Stations
  • Energy Saving Irrigation Systems
