The shut-off valve is a kind of forced sealing valve because the valve stem will impose pressure to the valve flap to ensure no leakage on the sealing surface as the valve is closed. It features reasonable design, good sealing performance, small flowing resistance, quick opening and closing, easy maintenance, and wear proof behavior of the sealing surface. The shut-off valve is very suitable for the cases where corrosion and friction-resistant application and cut-off function are required and is quite popular in pipeline systems of chemical, shipbuilding, medicine industries and food machinery, etc.
