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
