Electric Actuator Controls: Operation, Failures, and Troubleshooting
Electric actuators are essential components in modern control systems, conv...
HEA-P series spring return electric actuator is designed for fail-safe positioning of valves or dampers upon loss of supply voltage .Mechanical spring return design is used to position controlled devices to either fully open or fully closed positions without any external power source.
| 1.Product Construction Compact and designed for small spaces. |
 |
4.Secure Operation Under critical conditions, this product provides excellent guarantee stability with mechanical solutions. Spring return electric actuator generates the required torque through energy storage mechanism for returning to safe position with no assistance during the spring return operation process. |
| 2.Low Maintenance Durable hassle-free operation. Spring effectively drives a 90°full stroke. Emergency on/off model employs a mechanical buffer without impacting pipes. |
5.Position Detection Stroke control switch with quick set up and reliability. Three dimensional indicator can be monitored in multi angles. Optional with switching value and analog quantity control. |
|
| 3.Secure And Stable Spring return electric actuator complies with SIL2/SIL3 standard regulations and is maintenance-free with anti-explosion applications. |
6.Adaptive Connection Parts Actuator flange and drive sleeves comply with ISO5211 standards. A versatile design that offers its replacement. |
