Filter Backwash Hydraulic Valve IR-170-beU

Filter Backwash Hydraulic Valve IR-170-beU

The BERMAD Filter Backwash Flow Control Valve is a hydraulically operated, diaphragm actuated control valve that limits filter system backwash flow to a constant preset maximum. This eliminates the risk of filtration element collapse or of filter grains being flushed out.

  • Line pressure driven Hydraulic Flow Control

-Prevents flushing out of grains or filtration element collapse

  • Servo Flow Pilot Controlled

-Dynamic integrated needle valve

-Very low hysteresis

-Easy flow setting

  • 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 actuation pressure

-Prevents diaphragm erosion and distortion

  • Hydraulic Flow Sensor (upstream installation)

-No moving parts

-No need for flow straightening

Typical Applications

  • Filter Stations
  • Systems Subject to Varying Supply Pressure
