KE Series Electric Actuator

Brand: A-T Controls, Inc

The TRIAC® KE Series electric actuators are the perfect match for small resilient or high-performance butterfly valves and dampers because of the self-locking worm drive and low profile that makes them ideal for tight spaces.

The KE Series actuators are used to control rotary valves, such as butterfly valves, ball valves, plug valves, etc.

Widely used in applications such as petroleum, chemical, water treatment, ship, paper, power stations, heating supply, building automation, light industry, etc.
