The pneumatic ball valve is a ball that rotates 90° around the axis of the valve stem to open and close. Pneumatic ball valves are mainly used on pipelines to cut off, distribute and change the flow direction of media. Pneumatic ball valves designed with V-shaped openings also have good flow regulation functions.
The pneumatic butterfly valve is different from the pneumatic ball valve. It is a valve that uses a disc-type opening and closing part to reciprocate about 90° to open, close and adjust the fluid channel.
Characteristics of pneumatic ball valve:
Blockage and secretion: When the valve is closed, the valve seats on the upstream and downstream sides block the liquid, and the stagnation in the cavity of the valve body can be secreted through the secretion device.
Automatic pressure relief structure: When the pressure in the side chamber increases abnormally, the medium in the middle chamber can rely on its own thrust to push the valve seat and automatically relieve the pressure, thereby ensuring the safety of the valve lift.
Reliable sealing of the valve stem: The valve stem adopts a bottom-mounted structure with an inverted seal. The sealing force of the inverted seal increases with the increase of the medium pressure, so the reliable sealing of the valve stem can be ensured. Moreover, when the valve stem increases abnormally, The valve stem will not spray out.
Fireproof structure: According to the working conditions and user needs, the ball valve can be planned as a fireproof structure.
Anti-static structure: When operating the valve, due to the friction between the ball and the valve seat, an electrostatic charge will be generated and accumulated on the ball. In order to prevent the occurrence of static sparks, an electrostatic device is specially installed on the valve to remove the charge accumulated on the ball. Charge derivation.
