Flow Control and Pressure Reducing Valve IR-172-bDZ

The BERMAD Flow Control and Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that limits system demand and reduces downstream pressure to constant preset maximum values.

  • Line Pressure Driven Hydraulic Flow Control

-Limits fill-up rate and consumer over-demand

-Protects downstream system

  • Adjustable Servo Flow Pilot and 2-Way Pressure Reducing Pilot Controlled

-Very low hysteresis

-Easy flow and pressure setting

  • Engineered Plastic Valve with Industrial Grade Design

-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 Guided Plug

-Accurate and stable regulation with smooth closing

-Requires low actuation pressure

-Prevents diaphragm erosion and distortion

  • Internal “Differential Pressure Duct” Flow Sensor

-No moving parts

-Saves space and simplifies installation

Typical Applications

  • Line Fill-Up Control
  • Pressure Reducing Systems
  • Multiple Independent Consumer Systems
  • Systems Subject to Varying Supply Pressure
