Product: Pneumatic ball valve with 3 position actuator


Introduction


Pneumatic ball valve with 3 position actuator is a shut-off valve that can realize two-step opening or two-step closing action. This device relies on two sets of solenoid valves to control the flow of the valve. Due to the fast exhaust and throttling functions in the actuator,  the opening and closing speed of the ball valve is slowed down and the fluid in the pipeline changes relatively smoothly. In this way the flammable fluid will not explode due to the water hammer phenomenon caused by the impact and damage the flowmeter and other instruments in the system.




How the 3 position actuator works


Position 1 (middle position)

Air source pressure enters port 2 and port D at the same time, air is discharged from port 4 and port C, port 2 moves as an internal piston, and port D is limited by the auxiliary piston push rod to limit the internal piston to be positioned at a predetermined intermediate position.


Position 2 (full open position)

The air source pressure enters port 2 and port C at the same time, the air is discharged from port 4 and port D, and the internal piston of port 2 continues to move.



Position 3 (full closed position)

Air source pressure enters port 4, air is discharged from port 2, and the internal piston moves to the middle direction to reach the fully closed position. 0-45-90 spring-return models are available. When the air is cut off or the air supply fails, the internal piston is forced to return to the fully closed position by the spring.




Features


1.   Compact structure, quick response and easy maintenance ;

2.    The sealing structure is divided into soft elastic sealing metal seal, which can be used separately in different conditions ;

3.    The actuator can be equipped with limit switch and optional accessories to automate various types of operation ;

4.    Manual gearbox can be mounted at the bottom of the actuator for emergency operation;

5.    Blow-off stem and anti-static design.
