Bermad Model 120 - 3 way Pressure Reducing Valve

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.

PRODUCT CODE:
120-3W-XXX
SIZE RANGE:
40-150 mm

Features and Benefits

  • Line pressure driven Hydraulic Level Control
    - Protects downstream systems
    - Opens fully upon line pressure drop
  • Engineered Plastic Valve with Industrial Grade Design
    - Adaptable on-site to a wide range of end connection sizes and types
    - Articulated flange connections isolate valve from line bending and pressure stresses
  • Highly durable, chemical & cavitation resistant hYflow ‘Y’ Valve Body with “Look Through” Design
    - Ultra-high flow capacity at Low pressure loss
  • Unitized Flexible Super Travel Diaphragm with a Guided Plug
  • Accurate and stable regulation with smooth closing
  • Requires low actuation pressure
  • Prevents diaphragm erosion and distortion
  • Simple In-Line Inspection and Service

Operation

Bermad Model 120 - 3 Way Solenoid Valve - Operation

The Pressure Reducing Pilot [1] commands the main Valve to throttle closed should Downstream Pressure [P2] rise above pilot setting, and to open fully when it drops below pilot setting. The Manual Selector [2] enables local manual closing
