Generally used for high-pressure valves (1500LB, 2500LB, etc.) According to this form of movement of the valve flap, the change of the valve seat port is proportional to the stroke of the valve flap. Because the valve rod opening or closing stroke is relatively short, and has a very reliable cut-off function. 1. The structure is simple, and it is more convenient to manufacture and maintain. 2. The working schedule is small, and the opening and closing time is short. 3. Good sealing performance, low friction between sealing surfaces and long service life. Precautions 1. The cut-off valve operated by hand wheel and handle can be installed at any position of the pipeline. 2. Handwheels, handles and moving mechanisms are not allowed to be used for lifting. 3. The flow direction of the medium should be consistent with the arrow direction shown in the valve body.
