高压止回阀

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.

锻钢旋启式止回阀是一种紧凑、高性能的解决方案，专为小型管道（DN15-DN50）的逆流防止而设计。该阀门采用精密锻造结构和轻质旋启式阀瓣，确保在仪表、取样和公用工程系统中实现可靠的单向流量控制。该阀门自动运行，不适用于流量调节。.

2500LB高压轴流式止回阀专为在高要求应用中承受极端压力而设计。该阀门额定压力为2500 PSI（2500LB），可确保可靠且安全的单向流体流动，并具备强大的防倒流功能。其轴流式设计及硬密封面使其成为石油天然气、发电及石化加工等行业高压管道的理想选择。该阀门能够应对严苛的运行工况，同时确保最佳性能与耐久性。.
