Bermad Model 130 - 3 way Pressure Sustaining Valve
The BERMAD Pressure 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.
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 smooth closing - Requires low opening and actuation pressure - Prevents diaphragm erosion and distortion
The Pressure Sustaining Pilot  commands the main Valve to throttle closed should Upstream Pressure [P1] drop below setting, and to open fully when [P1] rises above setting. The Manual Selector  enables local manual closing.
