Pressure Relief/Sustaining Valve IR-130-50

The BERMAD Pressure Relief/Sustaining Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure. It either opens or shuts in response to a remote pressure command. When installed offline, the BERMAD Model IR-130-50 relieves line pressure in excess of preset pressure.

  • Line Pressure Driven, Hydraulically Controlled On/Off

-Sustains upstream line pressure controlling system fill-up

-Relieves excess pressure protecting pump & system

  • Engineered Plastic Valve with Industrial Grade Design

-Adaptable on-site to a wide range of end connection sizes and types

-Articulated flange connections eliminate mechanical and hydraulic stresses

-Highly durable, chemical and cavitation resistant

  • 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

  • Simple In-Line Inspection and Service.
