Ultra High Flow Valves


The Ultra High Flow Valves are designed for overpressure and vacuum relief. Available in 3 standard sizes of 1”, 3” and 8” (25mm, 76mm and 200mm), the Ultra High Flow Valve offers a significantly higher increase in gas pass-through compared to other similar-sized valves due to its unique characteristics (After opening completely, there is a proportional decline in backpressure). The valve can be used for various applications, such as overpressure in pressure vessels, pipelines, storage vessels, safety relief applications, and equipment containers. It can react within 0.2 seconds and resets after opening, even after achieving the limit of flow performance. The Ultra High Flow Valve range from the standard pressure settings from 0.5 psi to 5.0 psi for pressure and vacuum relief. These valves can function in rough environments such as driving rain, corrosive chemicals, and low and high temperatures. Additional options include debris filter, EMC screening, manual relief override, and additional mechanical and physical protection.

Key Features

  • Available in three sizes
  • A faster reaction time of 0.2 seconds after high pressure is detected. After depressurisation, it resets quickly too
  • Able to function in adverse environments
  • Easy to install
