However, in high - pressure applications, larger gate valves may be designed with more robust sealing mechanisms. The larger size allows for the use of thicker and more durable sealing materials, and the valve can be engineered to withstand higher sealing forces. Till exempel,API 6A grindventil
Valet av ställdon för en slussventil beror på dess storlek och driftsförhållandena. For small gate valves, a simple manual handwheel or a small - sized electric or pneumatic actuator may be sufficient. However, for large gate valves, hydraulic actuators are often used due to their ability to provide high torque.
Different sizes of gate valves are suitable for different applications. Small gate valves are commonly used in residential plumbing, laboratory equipment, and small - scale industrial processes where the flow rate and pressure are relatively low. Till exempel, en
