VM-32AG: Angular Stroke Drive, Precision Rotation! Rack-and-Pinion Pneumatic Actuator Empowers Valve Automation

In applications requiring automated control of rotary valves such as ball valves, butterfly valves, and plug valves, electric actuators are often costly and complex, while traditional cylinders cannot directly output rotational motion. The VM-32AG Pneumatic Actuator is specifically designed to drive valves with 90° rotation. Featuring a compact structure, reliable output torque, and flexible mounting options, it serves as an economical and efficient solution for valve automation control. Core Product Advantages

• 90° Angular Stroke Output Specifically engineered to drive valves requiring 90° (quarter-turn) rotation. The output shaft directly drives the valve stem, eliminating the need for additional linkage mechanisms. This results in a compact design and easy installation.
• High-Efficiency Rack-and-Pinion Transmission Utilizes a rack-and-pinion or piston-rack transmission mechanism to efficiently convert the linear motion of the cylinder into rotary motion. It delivers high output torque, smooth operation, and rapid opening/closing.
• Double-Acting & Spring-Return Options Offers both double-acting (air to open, air to close) and single-acting spring-return (air to open/close, spring automatically returns upon air loss) types to meet different safety and control requirements.
• Compact and Lightweight Design Features a compact structure, light weight, and small footprint, making it easy to integrate with various valves.
• Rich Selection of Accessories Can be equipped with accessories such as limit switches, solenoid valves, positioners, and handwheels to enable position indication, remote control, modulation, and manual operation.

Typical Application Scenarios

• Valve Automation:​ Automating the opening and closing of ball valves, butterfly valves, and plug valves.
• Process Control:​ Applied in pipeline fluid control within industries such as oil & gas, chemical, water treatment, and power.
• Safety Shut-off:​ Serving as the actuator for Emergency Shutdown Valves (ESD), enabling rapid fluid shutoff in hazardous situations.

Technical Parameters (Typical Values)

• Drive Type: Pneumatic (Double-Acting / Single-Acting Spring-Return)
• Angular Stroke: 90° (other angles, e.g., 180°, may be available)
• Output Torque: XX N·m (@0.4/0.6MPa, refer to manual)
• Operating Pressure: 0.2 ~ 0.8 MPa
• Interface: Standard ISO 5211 mounting interface for easy connection to valves
• Operating Temperature: -20°C ~ +80°C
