For industrial applications requiring precise butterfly valve control in tight spaces, compact pneumatic rotary actuators deliver 90° rotation with reliable torque output (typically 10-500 Nm). These lightweight yet powerful actuators are ideal for HVAC, water treatment, and chemical processing systems where installation space is limited.
Key Benefits:
✔ Space-Optimized Design: 30-50% smaller than standard actuators while maintaining equivalent torque
✔ Butterfly Valve Compatibility: Direct ISO 5211 mounting (F03-F14 flanges)
✔ Fast Response Time: 0.5-2 second operation cycle for rapid flow control
✔ Durable Construction: Aluminum housing with stainless steel shafts (optional IP67 protection)
Technical Highlights:
- Double-acting/Spring-return configurations
- Adjustable end stops for precise angular positioning
- Low-friction seals for >1 million cycles maintenance-free operation
Leading Chinese manufacturers offer OEM customization on:
• Torque output (certified to EN 15714-3)
• Temperature range (-40°C to +150°C with special seals)
• Explosion-proof versions (ATEX/ IECEx)
Pro Tip: When selecting, match actuator torque to valve breakaway torque with 25% safety margin. Request CFD-tested models for high-cycle applications.
(For technical drawings and MOQ details, contact actuator suppliers directly with your valve size and pressure requirements.)
