Veson Pneumatic Actuator 120°, 135°, 180° double acting 4th Generation actuators provide rotations of 120°, 135° or 180°. The external travel stop is available as a standard in fully open position (120°, 135° or 180°) and in fully close position (0°), and it is easily and precisely adjustable of +/- 4° in both directions. Fields of application: 3 or 4 way valves, special valves for sample taking and any applications where a 120°, 135° or 180° rotation is required.
Product: Three Position Pneumatic Actuator
Introduction
This model is configured for three-position operation of valves , 0°-45°-90° or 0°-90°-180°. It can pause and maintain at the certain position during the valve travel.
How the 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. Adjustable positioning nuts;
2. Body surface anodic oxidated and Nickel plated;

The 3-position pneumatic actuator can be used with various types of valves depending on the specific application requirements. It is commonly employed with valves that require three distinct positions or modes of operation, such as:
Butterfly Valve: The 3-position pneumatic actuator can be used to control the opening and closing of butterfly valves, which are quarter-turn valves with a disc-shaped closure element.
Ball Valve: Ball valves, which use a spherical closure element, can be operated by a 3-position pneumatic actuator to achieve full open, full closed, and intermediate positions.
Plug Valve: The 3-position pneumatic actuator can control the movement of the cylindrical or conical plug in plug valves, allowing for three different flow conditions.
Diverter Valve: Diverter valves, which redirect flow from one channel to another, can benefit from a 3-position pneumatic actuator to accurately position the diverter element.
Slide Valve: Slide valves, also known as gate valves, can utilize the 3-position pneumatic actuator to achieve precise positioning of the sliding gate for flow control.
Control Valve: In certain applications, the 3-position pneumatic actuator can be used in conjunction with control valves, allowing for three distinct control modes or positions.
It's important to note that the compatibility of the 3-position pneumatic actuator with specific valves may vary based on factors such as valve size, design, and the actuator's operating parameters. Therefore, it's essential to select the appropriate actuator and valve combination based on the intended application and system requirements.
