JIS 16K Angle Screw-Down Check Valve
JIS 16K angle screw-down check valve adopts upgraded thickened body structure to withstand 1.6MPa high pressure, far exceeding the bearing capacity of 5K and 10K models. It integrates manual screw shut-off and automatic check functions with 90° angle flow design for low flow resistance and zero-leakage performance.
Overview
Application:It is widely used on high-pressure steam, cooling and process pipelines of ships, chemical equipment and industrial piping systems.It serves critical pipelines requiring both pipeline isolation and strict anti-reflux protection to safeguard upstream and downstream devices.
