H12W-16P stainless steelVertical check valve function is used to prevent the backflow of the medium in the pipeline. Check valve belongs to the automatic valve category, the opening and closing parts rely on the force of the flowing medium to open or close. Check valve is only used for one-way flow of media on the pipeline, to prevent the media backflow.
Product Features
- Features a compact structure, small size, and light weight.
- The valve disc closes rapidly, minimizing water hammer pressure.
- The flow path is unobstructed, resulting in low fluid resistance; it operates with high responsiveness and excellent sealing performance.
- Easy to install, suitable for both horizontal and vertical pipe installations.
- The valve plate incorporates a design featuring a torque spring mounted on the counterplate, enabling the valve plate to close rapidly on its own.
- The rapid closing action prevents backflow of the medium and effectively eliminates water hammer effects.
