Pressure Reducing and Sustaining Valve IR-123-XZ

The BERMAD Model IR-123-XZ is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and reduces downstream pressure to a constant preset maximum.

Product Features & Benefits
  • Line Pressure Driven, Hydraulically Controlled

-Protects downstream system

-Prioritizes pressure zones

-Controls system fill-up

  • Engineered Plastic Valve with Industrial Grade Design

-Highly durable, chemical and cavitation resistant

-No internal bolts and nuts

  • hYflow ‘Y’ Valve Body with “Look Through” Design

-Ultra-high flow capacity – Low pressure loss

  • Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug

-Accurate and stable regulation with smooth closing

-Requires low opening and actuation pressure

-Prevents diaphragm erosion and distortion

  • User-Friendly Design

-Easy pressure setting

-Simple in-line inspection and service
