High pressure wafer check valve
The High Pressure Wafer Check Valve is an ultra‑short pattern check valve designed for high‑pressure pipelines. It typically features a dual‑plate (twin disc) or spring‑loaded single‑plate design, where the discs rotate around a central pin shaft to allow unidirectional flow. Compared with traditional flanged swing check valves, the wafer type offers a face‑to‑face length that is only 1/3 to 1/5 that of conventional valves, resulting in lighter weight, smaller installation space, and reduced pipeline loads.

Micro Resistance Slow Closing Check Valve
The Micro Resistance Slow Closing Check Valve is an energy‑saving check valve specifically designed for pump discharge applications, featuring a slow‑closing function. It combines the low flow resistance characteristics of a swing check valve with a hydraulic damping device. During forward flow, the disc opens to a large angle with minimal resistance; when the pump stops or backflow occurs, the disc first closes rapidly for most of its travel, then closes slowly for the remaining travel, thereby greatly reducing water hammer pressure peaks and protecting the pump and pipeline system.
Large diameter check valve
The Large Diameter Check Valve is a high-performance, butterfly-style non-return valve designed for large-scale piping systems requiring reliable flow control and water hammer prevention.
