EPC Electric Actuator

Description

EPC Electric Actuator:

The EPC Electric Actuator is a supercapacitor-powered reset actuator designed for critical valve control applications. In the event of a power failure, it ensures reliable valve closure or positioning without external power using its built-in capacitor — offering stronger return force than spring-return types. It features a compact design, high torque output, wide voltage range, IP67/IP68 protection, and ISO5211 compatibility. Ideal for industrial and marine environments requiring high reliability and safety.
