The safety valves VS 224 are designed and manufactured by Epe Italiana. They have soft seal and total lift. They have a high flow coefficient (K = 0.95) and are suitable for gas and liquids.

These valves are direct acting safety valves, used for protection against overpressure with respect to the operating conditions of the accumulators. They can be installed directly on the accumulator, through the appropriate use of adapters or on the safety block gas side (BC32G) or on manifold on the gas side of the accumulator stations.
