Shut-Off Valve Note:
1. The use of Shut-Off Valve is extremely common, but due to the large opening and closing torque and long structural length, the nominal diameter is usually limited to 250mm or less, but also to 400mm, but special attention should be paid to the direction of inlet and outlet.
2. Generally, the shut-off valve medium below 15Omm mostly flows from below the valve flap, and the shut-off valve medium above 2O0mm mostly flows from above the valve flap.
3. Globe valves are available in most media flow systems. Various forms of shut-off valve have been developed to meet various uses of petrochemical, electric power, metallurgy, urban construction, and chemical industries.
4. The flow resistance coefficient of the shut-off valve is relatively large, thus causing pressure loss, especially in hydraulic devices, such pressure loss is particularly obvious.
