Product Description
The BERMAD Flow Control Valve with Hydraulic Control is a hydraulically operated, diaphragm-actuated control valve that limits system demand to a preset maximum flow rate.
Features and Benefits
- Line Pressure Driven Hydraulic Flow Control
- Limits fill-up rate and consumer over-demand
- Adjustable Servo Flow Pilot Controlled
- Dynamic integrated needle valve
- 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
- Internal “Differential Pressure Duct” Flow Sensor
- No moving parts
- Saves space and simplifies installation

Technical Data
Operation
Pressure Differential [ΔP] across the Differential Pressure Duct [1] is in direct proportion to demand. The Flow Pilot [2] continuously senses [ΔP] commanding the Valve to throttle closed should demand rise above the pilot setting, and to modulate open when demand is below the pilot setting. The Manual Selector [3] enables local manual closing.
