Quick Pressure Relief Valve

100 – SERIES IR-13Q
    Features and Benefits:
  • It is a hydraulically operated, diaphragm actuated control valve that relieves 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.
  • Unitized flexible super travel (FST) diaphragm and guided plug:
    a) Accurate and stable regulation with smooth closing.
    b) Requires low opening and actuation pressure.
    c) Prevents diaphragm erosion and distortion.
  • User friendly design, Easy pressure setting & simple in-line inspection and service.
  • Engineered plastic valve with industrial grade design.
  • Highly durable, chemical and cavitation resistant.
  • Adaptable on-site to a wide range of end connection sizes and types.
