Three-stage pneumatic actuator

The three-stage pneumatic actuator consists of an actuator housing and two actuator cylinders. Its three-stage structure (housing + dual cylinders) enables multi-position control. A key feature is the ability to fine-tune bolt positions, preventing cylinder rupture from excessive force while supporting partial-stroke control (e.g., 0°-45°-90° or 0°-90°-180°).

Technical Features

‌Fine-Tuning Design: Rotating the control rod drives the driven gear to turn slightly, enabling precise adjustment of bolt position to prevent piston pin disengagement or cylinder damage.

‌Material Optimization: The cylinder body adopts a profile structure while the piston is made of cast iron, balancing strength and cost; select premium models utilize aluminum alloy with anodized or plastic-coated finishes for enhanced corrosion resistance.

‌‌Performance Parameters‌:

Bore Range: 50mm–1000mm.

Stroke Angle: 90°, 120°, 180° (customizable in increments from 20°–175°).

Seal Temperature Resistance: -40°C to +150°C (varies by material).

Applications

‌Quantity Control Systems: Used in quantitative loading and filling systems, achieving precise flow regulation through multi-stage control.

‌Industrial Valve Actuation: Compatible with ball valves, butterfly valves, plug valves, etc., particularly suited for applications requiring multi-position switching.

‌High-Purity Environments: Suitable for pharmaceutical and food industries, requiring use with sanitary-grade valves.
