PPR Pipe Fittings Vertical Check Valve

      DUNYUN PPR vertical check valves are one-way fluid control valves designed based on the material properties of PPR. Their core function is to prevent medium backflow, avoid damage to piping systems, water pumps, water tanks and other equipment caused by water hammer and backflow, and maintain stable system pressure simultaneously.

      Homogeneously compatible with PPR pipes, the PPR check valve can be connected via hot melting, featuring hygienic and environmentally friendly properties as well as heat and pressure resistance.

      They are mainly applied in cold and hot water systems, drinking water transmission, and small-scale HVAC/circulating water systems in civil buildings.
