PRODUCTS

1. The check valve products are designed and manufactured in accordance with BS1868 and API6D, with reliable sealing and excellent performance.

2. The sealing surfaces of the disc and seat are made by surfacing with stellite cobalt-based hard alloy, which is wear-resistant, heat-resistant, has good scratch resistance and a long service life.

3. Various pipe flange standards and flange sealing surface types can be adopted to meet the needs of various projects and user requirements.

4. The valve body materials are complete in variety. The packing and gasket are reasonably selected according to the actual working conditions or the user's requirements, which can be applied to various pressure, temperature and medium working conditions.

5. Check valves of different structural and connection forms can be manufactured according to the user's requirements to be used in conjunction with various equipment.
