The Ultra High Flow Valves are developed for overpressure and vacuum relief applications. It is available in three standard sizes of 1”, 3” and 8” (25mm, 76mm, and 200mm). These are ideal for a range of applications, such as overpressure in pressure vessels, pipelines, equipment containers storage vessels, and safety relief applications. These react within 0.2 seconds and resets even after achieving the limit of flow performance. The ultra-high flow valves range from the standard pressure settings from 0.5 psi to 5.0 psi. These can function in adverse environments, including driving rain, corrosive chemicals, and low and high temperatures.
