The body structure of the lift check valve adopts the body of the globe valve, and the valve flap moves along the channel in a line for lifting, which is reliable, but the fluid resistance is large, and it is suitable for light and small caliber occasions. Straight lift check valve can only be installed in the horizontal pipeline, while the vertical lift check valve is generally installed in the vertical pipeline. Products are widely used in petroleum, chemical, pharmaceutical, electric power industry and other working conditions of the pipeline.
1, check valve product design and manufacture according to the design and manufacture inspection, reliable sealing, excellent performance.
2、The sealing surface of valve flap and valve seat is made of Stearic cobalt-based hard alloy, which is wear-resistant, high temperature resistant, good anti-scuffing performance and long service life.
3, can adopt a variety of piping flange standards and flange sealing surface type, to meet the needs of various projects and user requirements.
4、The valve body material variety is complete, packing, gasket according to the actual working conditions or user requirements reasonable matching, can be applied to a variety of pressure, temperature and media working conditions.
5, can be manufactured according to user requirements of different structural forms and connection forms of check valve, for a variety of equipment supporting the use.
