Bermad - Model 205 - Basic Hydraulic Valve

Product Description

The BERMAD Model 220-55 2-Way Pressure Reducing Valve with Solenoid Control 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. This model either opens or shuts in response to an electric signal.

Features and Benefits

  • Line Pressure Driven, Electrically Controlled On/Off
    • 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 path
    • 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 - 220-55-2W - Operation

The Shuttle Valve [1] hydraulically connects the Solenoid [2] or the Pressure Reducing Servo Pilot (PRSP) [3] to the Valve Control Chamber [4]. When the solenoid is closed, the PRSP commands the Valve to throttle closed, preventing Downstream Pressure [P2] from rising above the pilot setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber. This causes the Valve to shut. The solenoid also features local manual closing.
