Engineering Data:

Bermad - Model 205 - Basic Hydraulic Valve

Product Description

The BERMAD Pressure Reducing Control Valve with Solenoid Control is a hydraulically operated, diaphragm-actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand and opens fully upon line pressure drop. The BERMAD Model 220-55-X 3W either opens or shuts in response to an electric signal.

Features & Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Protects downstream systems
    • Opens fully upon line pressure drop
    • Electrically controlled On/Off
  • Smooth valve opening and closing
    • Accurate and stable regulation
    • Low operating pressure requirements
  • 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 - 220-55-3W - Operation

The Shuttle Valve 1 hydraulically connects the Solenoid 2 or the Pressure Reducing Pilot (PRP) 3 to the Valve Control Chamber 4. When the solenoid is closed, the PRP commands the Valve to throttle closed should Downstream Pressure P2 rise above the setting and to open fully when P2 is below the setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber, shutting the Valve. The solenoid also features local manual closing.
