Lift check valve performance characteristics according to GB12235 standard, valve flap along the center positioning for lifting movement, the liner is made of materials with good performance and small friction coefficient, action, sealing performance is excellent. The products are used in petroleum, chemical, thermal power station and other various working conditions of the pipeline, applicable medium for water, oil, steam and so on. The main role is to prevent the medium backflow, to prevent the pump and its driving motor machine reversal, as well as the discharge of the medium in the container.

Lift check valve can automatically stop the fluid backflow, mainly used to control corrosive or strong corrosive media, the valve body cavity surface covered with optional fluorine plastic, with good corrosion resistance, suitable for different work temperature and fluid pipeline, so as not to pipeline or equipment on the media backflow check valve. Lift check valve can only be installed in the horizontal pipeline.

Lift check valve product structure is reasonable, reliable sealing, excellent performance, beautiful modeling, sealing surface surfacing Co hard alloy, wear-resistant, corrosion-resistant, anti-friction performance, long service life, stem tempering and surface nitriding treatment, good corrosion resistance and anti-friction performance, double sealing, performance is more reliable, more intuitive indication of the lifting position of the valve stem, parts materials, flanges and butt weld dimensions can be reasonably selected according to the actual conditions or user requirements to meet a variety of engineering requirements. The material of parts, flange and butt-welding size can be reasonably selected according to the actual working conditions or user's requirements to meet various engineering needs.
