JIS 5K Swing Check Valve

JIS 5K swing check valve uses a swing disc that opens and closes with medium flow, enabling automatic one-way sealing without manual operation. Its wide straight-through inner cavity effectively lowers pressure loss when the medium passes through the valve body.

Overview

Application:It is installed on low-pressure fresh water, ballast water and drainage pipelines of various ships to avoid liquid backflow and system reverse impact. It is also applicable to municipal and general industrial pipelines needing passive anti-reflux protection.
