Are pneumatic valve metal fittings used to drive pneumatic valves?

The pneumatic valve metal fittings themselves cannot be directly used to drive pneumatic valves. The driving of pneumatic valves usually relies on compressed air as the power source, and the valve is opened and closed through pneumatic actuators (such as cylinders).
In the composition of pneumatic valves, metal accessories such as valve seats, sealing rings, valve shafts, etc. mainly play a supporting, sealing, and connecting role to ensure the normal operation and sealing performance of the valve. For example, a valve seat is a seat plate that supports the valve and seal, usually made of metal or plastic; The sealing ring is an important component to prevent gas leakage, usually installed on the valve seat plate, piston rod, and valve shaft; The valve shaft is the main component that supports the movement of the valve, usually made of stainless steel.
The driving of pneumatic valves relies on the pneumatic actuator, which is the core part of pneumatic valves, including cylinders and valve positioners. The cylinder is driven by gas to open or close the pneumatic valve, thereby controlling the flow of the medium; The valve locator is responsible for adjusting the position of the cylinder switch to ensure precise control of the cylinder and stability of the valve.
Therefore, although pneumatic valve metal fittings play a crucial role in the operation of pneumatic valves, they themselves cannot be directly used to drive pneumatic valves.
