Spring Return Pneumatic Actuators
Reliable Valve Control for Industrial and Commercial Applications
Yes, spring return pneumatic actuators are widely and effectively used for valve control across various industrial and commercial applications. Their design and functional characteristics make them well-suited to regulate the opening, closing, and positioning of different types of valves.
- Consistent Torque Generation Valves need sufficient force to overcome internal pressure and friction. Spring return pneumatic actuators deliver this force through compressed air, which drives the actuator's cylinder to move the valve's stem or disc.
- Fail-Safe Operation The integrated spring plays a vital role: in case of air pressure loss, it automatically returns the valve to a pre-set "fail-safe" position—either fully open or fully closed. This is especially valuable for valves in critical systems.
- Adaptability to Valve Types They work seamlessly with on-off valves (like ball valves, gate valves, and butterfly valves). When paired with positioners, they can control modulating valves which need incremental adjustments to regulate flow rate.
- Durability in Harsh Environments Built with corrosion-resistant metals and robust polymers, enabling them to withstand harsh conditions like high humidity, temperature fluctuations, or exposure to chemicals.
