BERMAD Irrigation 100 Series h Yflow Flow Control & Pressure Reducing Flow Control and Pressure Reducing Valve IR-172-bDZ The BERMAD Flow Control and Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that limits system demand and reduces downstream pressure to constant preset maximum values. Line Pressure Driven Hydraulic Flow Control Limits fill-up rate and consumer over-demand ❏ Protects downstream system Adjustable Servo Flow Pilot and 2-Way Pressure Reducing Pilot Controlled ❏ Very low hysteresis ❏ Easy flow and pressure 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 ❏ Line Fill-Up Control Pressure Reducing Systems Multiple Independent Consumer Systems Systems Subject to Varying Supply Pressure [1] BERMAD Model IR-172-bDZ protects supply system from excessive flow, limits fill-up rate and consumer over-demand, and establishes reduced higher pressure zone.
