The check valve is automatically opened and closed by the force generated by the flow of the medium in the pipeline, and belongs to an automatic valve. Check valve is used for pipeline system. Its main function is to prevent the media flowing backwards and bleeding from the container. Check valves may also be used for piping where the pressure may be increased to the auxiliary system that exceeds the main system pressure.
The sluice valve uses the austenite stainless steel, which has good corrosion resistance to the oxidizing acid medium. The medium flow through stainless steel sluice valve does not change its flow direction, and the fluid resistance is small. The direction of the ram movement is perpendicular to the flow direction of the medium, and the opening and closing moment is small, and the opening and closing is easier. The shutter is vertically placed in the valve body and the structure is short. The sealing performance is good. When fully open, the sealing surface is less erosion.
The right-angle cut-off valve is suitable for the pipeline of various working conditions in various industries, cutting off or connecting the pipeline medium. It has reasonable structure, reliable sealing, good performance and beautiful shape. The sealing surface of co - based cemented carbide has good wear resistance, corrosion resistance, no leakage, good friction resistance and long service life. Stem quenching and surface nitriding treatment have good corrosion resistance and friction resistance. The sealing property is more reliable.
