All pressurised systems, conforming to the appropriate National and International standards, are limited to a maximum overpressure during pressure relief. The maximum pressure is limited according to the applicable standard, whether its AS1210, AS 1358, ASME V111 or the European PED – pressure equipment directive.

Our pressure relief devices include Rupture Discs, Pressure and vacuum relief valves, Pseudo Pin pressure relief valves for primary and secondary relief applications.

KITO is regarded as a world leader in the design and manufacture of tank protection, and access valves to limit the pressure and vacuum created by changes in atmospheric pressure. As pressure rises or falls, KITO pressure relief valves allow the tank to breathe, preventing damage and spillage to ensure the safety of personnel and the surrounding environment. KITO pressure relief valves, vacuum relief valves, and combined pressure and vacuum relief valves can be weight, spring, or pilot-operated and combined with KITO flame arresters for end-of-line applications.

The Guardian pseudo pin pressure relief valve is a quick-opening, full-line capacity pressure relief valve. It uses force vectoring and pseudo-pin technology to eliminate pins, seals, and membranes required by traditional pin valves. This patent pending design is superior to current pin valves due to the repeatability across a broad range of set pressures and service conditions.
