Pressure Reducing Valve IR-120

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

  • Hydraulic Pressure Control

-Line pressure driven

-Protects downstream systems

  • Engineered Plastic Valve with Industrial Grade Design

-Adaptable on-site to a wide 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 setting

-Simple in-line inspection and service

Typical Applications

  • Pressure Reducing Stations
  • Low Supplied Pressure Irrigation Systems
  • Energy Saving Irrigation Systems
