Introducing a new range of Ultra High Flow Relief Valves in three standard sizes of 1", 3" and 8" (25 mm, 76 mm and 200 mm). A unique operating characteristic for this pressure relief valve is proportional decrease in back pressure after the relief valve has opened at the set pressure and increased flow is required.
This allows a significantly high increase in gas flow when compared to similar size pressure relief valves. These valves are ideal for rapid decompression or explosive decompression requirements. Additionally, these valves are suitable for over pressures in pipelines, pressure vessels, storage vessels, equipment containers and safety relief applications.
The standard specification for pressure settings is from 0.5 to 5 psi for opening pressures and vacuum relief. The pressure relief valve can operate in aggressive environments, including corrosive chemicals, driving rain, and low and high temperatures. A weather and impact shield provides further mechanical and physical protection.
Additional optional features include: debris filter, EMC screening and manual relief override.
RFI/EMI shielding is available.
