Product Description

The BERMAD Pressure Model 130-X 3 Way Sustaining Valve is a hydraulically operated, diaphragm-actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.

Features and Benefits

  • Line Pressure Driven, Hydraulically Controlled
    • Prioritizes pressure zones
    • Controls system fill-up
    • Opens fully upon line pressure rise
  • Engineered Plastic Valve with Industrial Grade Design
    • Highly durable, chemical and cavitation resistant
    • No internal bolts and nuts
  • hYflow ‘Y’ Valve Body with "Look Through" Design
    • Ultra-high flow capacity –Low-pressure loss
  • Unitized Flexible Super Travel (FST) Diaphragm and Guided Plug
    • Accurate and stable regulation with the smooth closing
    • Requires low opening and actuation pressure
    • Prevents diaphragm erosion and distortion
  • Simple In-Line Inspection and Service

Technical Data

Operation

Bermad - 130-3W - Operation

The Pressure Sustaining Pilot [1] commands the main Valve to throttle closed should Upstream Pressure [P1] drops below the setting, and to open fully when [P1] rises above the setting. The Manual Selector [2] enables local manual closing.
