Description

Overview
The BERMAD Model IR-13Q-2W is a hydraulically operated, diaphragm actuated control valve designed to relieve excessive line pressure when it rises above the preset maximum. It responds to rises in system pressure immediately, accurately and with high repeatability, by opening fully. The IR-13Q-2W provides smooth drip-tight closing.

Hydraulic Control Valve
  • Line pressure driven
  • Short response time
  • Long term drip tight sealing

Engineered Composite Valve with Industrial Grade Design
  • Adaptable on-site to a wide range of end connections
  • Highly durable, chemical and cavitation resistant

hYflow 'Y' Valve Body with 'Look Through' Design
  • Ultra-high flow capacity at low pressure loss

Unitized 'Flexible Super Travel' (FST) Diaphragm and Guided Plug
  • Accurate and stable regulation with smooth closing
  • Requires low actuation pressure
  • Prevents diaphragm erosion and distortion
  • Simple in-line inspection and service

Typical Applications
  • System Burst Protection
  • Momentary Pressure Peak Elimination
