The Keystone EPI electric actuator is provided with a self-locking gear train that allows for a compact design. The product is standard equipped with a manual override, mechanical travel stops, epoxy coated aluminum housing, visual mechanical position indicator and adjustable limit switches. The EPI is designed for direct mounting to Keystone valves. General applications include valves or dampers. Particularly suitable for applications within process and associated markets, and network interfaces.
