Product Description

The BERMAD Model 120-3 Way 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 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 the 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 the smooth closing
    • Requires low actuation pressure
    • Prevents diaphragm erosion and distortion
    • Simple In-Line Inspection and Service
