BERMAD Irrigation 100 Series h Yflow Flow Control Flow Control Valve with Solenoid Control IR-170-55-bD The BERMAD Flow Control Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that limits system demand to a preset maximum flow rate. It either opens or shuts in response to an electric signal. Features and Benets Line Pressure Driven, Electrically Controlled On/Off Limits fill-up rate and consumer over-demand ■ Adjustable Servo Flow Pilot Controlled ❏ Dynamic integrated needle valve ■ Engineered Plastic Valve with Industrial Grade Design ❏ Adaptable on-site to a wide range of end connection sizes and types ❏ Articulated flange connections eliminate mechanical and hydraulic stresses ❏ 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 ■ Computerized Irrigation Systems Remote and/or Elevated Plots Line Fill-Up Control Multiple Independent Consumer Systems Distribution Centers Filter Stations [1] BERMAD Model IR-170-55-bD opens in response to an electric signal, limits fill-up rate and consumer over-demand, and maintains filter backwash pressure.
