The three-piece pneumatic ball valve is a ball valve equipped with a pneumatic actuator. It is a new type of valve.
The execution speed of pneumatic actuators is relatively fast and does not require workers to do it themselves, saving human resources and time to a large extent. Working principle of three-piece pneumatic ball valve
When the pneumatic actuator is connected to the circuit and system air source, air enters the cylinder (cylinder) through the pipe or tube to push the piston to move to one end, thereby driving the rotating shaft and the ball core to rotate.
The top of the pneumatic actuator is linked to the visual indicator. When the green mark points to the word "open", it indicates that the valve is open.
Introduction to the working principle of three-piece pneumatic ball valve
When the green light of the reply signal light is on, the valve is in the open position, and when the red light is on, the valve is in the closed position.
The positioner adjustable valve pipeline flow valve seat adopts an elastic sealing structure, which ensures reliable sealing and easy opening and closing.
The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally pressurized, the valve stem will not be impacted.
The pneumatic piston actuator is made of low-friction material as the bearing sleeve, and the outer and outer surfaces of the cylinder are treated with hard anodizing for anti-corrosion, which greatly extends the service life of the cylinder.
