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
