Flow Control and Pressure Reducing Valve IR-172-54-bD

The BERMAD Model IR-172-54-bD is a hydraulically operated, diaphragm actuated control valve that limits system demand and reduces downstream pressure to constant preset maximum values. It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

Product Features & Benefits

- Hydraulic Pressure Control, Normally Closed
  - - Closes upon control failure
  - - Limits fill-up rate and consumer over-demand
  - - Protects downstream system
  - - Amplifies and relays weak remote command

- Adjustable Servo and 2-Way Pilots
  - - Very low hysteresis, easy 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
