Product Description

The BERMAD Flow Control Valve is a hydraulically operated, diaphragm-actuated control valve that limits system demand to a constant preset maximum flow rate.

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Limits fill-up rate and consumer over-demand
  • Advanced Globe Hydro-Efficient Design
    • Unobstructed flow path
    • Single moving part
    • High flow capacity
  • Fully Supported & Balanced Diaphragm
    • Requires low opening and actuation pressure
    • Excellent low-flow regulation performance
    • Progressively restrains valve closing
    • Prevents diaphragm distortion
  • Hydraulic Flow Sensor (upstream installation)
    • No moving parts
    • No need for flow straightening
  • User-Friendly Design
    • Easy pressure setting
    • Simple in-line inspection and service
    • Easy addition of control features

Technical Data


Bermad - 47- Operation

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

Pressure Rating

  • 10 bar; 145 psi

Operating Pressure Range

  • 0.5-10 bar; 7-145 psi

For a lower pressure rating, consult Deeco.

Setting Range

  • ±20% from valve predetermined flow Orifice diameter is calculated in accordance with desired ΔP at predetermined flow.
    Although the standard calculated ΔP is 0.4 bar; 5.5 psi, the actual head loss is 0.2 bar; 2.8 psi.
