ZPP-2 and ZPP-2S are intended for underground and above-ground storage tanks for liquid substances. The valves are designed to automatically limit the flow of liquid during fuel delivery when it reaches the alarm level in the storage tank. They come in sizes 2", 3", 4" and 6". They are intended for gravity and pressure drainage, and their design limits the liquid flow to 95% at maximum closure. The remaining throughput of 5% allows the excess product contained in the tanker hose to be drained after turning off the main valve in the tanker. ZPP-2 are designed to work with non-aggressive media, in particular fuels. ZPP-2S version, made entirely of 316L acid-resistant steel, so it can work with all media, in particular biofuels, aviation fuels, alcohols, aggressive and food media. Thanks to its full construction of 316L acid-resistant steel, ZPP-2S does not require a hygienic certificate when used with food media.
