Product Description

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm-actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.

Features & Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Protects downstream systems
    • Opens fully upon line pressure drop
  • 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
