Bermad - Model 205 - Basic Hydraulic Valve

Product Description

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm-actuated control valve that accurately reduces higher upstream pressure to very low and stable preset downstream pressure regardless of fluctuating demand or varying upstream pressure.

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Protects downstream systems
  • Pressure Reducing Servo Pilot Controlled
    • Dynamic integrated needle valve
    • Easily settable to 0.5 bar; 7 psi
    • Very low hysteresis
  • Plastic Globe Hydro-Efficient Valve
    • Unobstructed flow pat
    • Single moving part
    • High flow capacity
    • Highly durable, chemical and cavitation resistant
  • Unitized Flexible Diaphragm and Guided Plug
    • Excellent low-flow regulation performance
    • Prevents diaphragm erosion and distortion
  • Fully Supported & Balanced Diaphragm
    • Requires low actuation pressure
  • User-Friendly Design
    • Simple in-line inspection and service

Technical Data


Bermad - 220-2W - Operation

The Pressure Reducing Servo Pilot [1] commands the Valve to throttle closed, preventing Downstream Pressure [P2] from rising above the pilot setting, and to modulate open when [P2] drops below the pilot setting. The Manual Selector [2] enables local manual closing.
