Pneumatic gate valve, with the help of a valve driven by compressed air, when the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface. It's self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.

Pneumatic globe valve is driven by a pneumatic device powered by compressed air. This type of valve has the characteristics of simple structure, reliable action, low failure rate and convenient maintenance. Therefore, it is widely used in thermal power plants, hydropower plants, nuclear power plants and other power plants. In general, this type of valve controls the action of the valve by remotely controlling the charging and discharging of compressed air. However, in order to prevent the accidental situation that the valve cannot be operated after the remote control method is lost, this type of valve is also equipped with a manual operating mechanism. When the remote control is in normal use, the manual operating mechanism must be in a certain position or area, otherwise the normal remote control action of the valve will be affected. It is usually stated that the manual operating mechanism needs to be adjusted to the "neutral point" position.

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The specific classification of pneumatic ball valves are: stainless steel pneumatic ball valve, plastic pneumatic ball valve, sanitary pneumatic ball valve, carbon steel pneumatic ball valve, two-way pneumatic ball valve, three-way pneumatic ball valve, four-way pneumatic ball valve.

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate that rotates with the valve stem to open and close to realize the activation action.
