Product Details

Product overview
The valve body structure of stainless steel lifting check valve adopts the valve body of the globe valve, and its disc is lifted and lowered along the channel with a line, which is reliable, but the fluid resistance is large, which is suitable for light and small caliber occasions. Straight-through lift check valves can generally only be installed in horizontal pipelines, while vertical lift check valves are generally installed in vertical pipelines. Products are widely used in petroleum, chemical, pharmaceutical, power industry and other working conditions of pipelines.

Product features
1. Check valve product design and manufacturing according to GB/T 12235 design and manufacturing inspection, reliable sealing, excellent performance.
2. The sealing surface of the valve disc and valve seat is made of stellite cobalt-based cemented carbide overlay welding, which is wear-resistant, high-temperature resistant, good scratch resistance and long service life.
3. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
4. The valve body has a complete variety of materials, and the packing and gasket are reasonably selected according to the actual working conditions or user requirements, which can be applied to various pressure, temperature and medium working conditions.
5. Check valves with different structures and connection forms can be manufactured according to user requirements, and used for various equipment.
