Flow Control Valve IR-170-54-bD

The BERMAD Normally Closed, Flow Control Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that limits system demand to a constant preset maximum flow rate. 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
