Stainless steel 316, compact design, high-pressure check valve H-400 & H-400HP series. A wide variety of packing materials available.

The H-400 series features a compact design for instrumentation panels and systems, with precise operating points. The H-400 check valve (non-return valve) is normally closed, and when the differential pressure between the inlet and outlet sides exceeds the spring's set pressure, the poppet moves in the opposite direction of the spring's pressing direction, opening the flow path within the valve to allow fluid to flow.

To meet customer applications, we also provide high-pressure types, one-piece types, and cracking pressure adjustment types. With a simple mechanism and easy installation, it protects equipment in the process line during abnormal conditions. <Features> - Available in standard type (H-400), high-pressure type (H-400HP), compact one-piece type (H-400OP), compact one-piece pressure adjustment type (H-400OPA), and pressure adjustment type (H-400A) - A wide range of cracking pressures available - A variety of sealing materials available - A variety of connections available - Spring kits and O-ring kits available *For more details, please download the PDF or feel free to contact us.
