Model ES2 Electric Actuator

Model ES2 is a light duty actuator designed for fail-safe applications. For best life expectancy it is recommended that model ES2 be powered in both clockwise (CW) and counter clockwise (CCW) directions. If used in this manner one can expect over 2,000 open/close cycles. When allowed to spring to the fail position as the normal model of operation, the life of the actuator is severely shortened. ES2 has a spring end torque of 200 in-lb with a closing speed of 3 sec./90° upon loss of power. This actuator is ideally suited for ball valves and dampers with torque ratings of up to 145 in-lb.

Standard equipment includes 115Vac-1ph 25% duty cycle motor with thermal overload protection, set to fail closed (CW rotation) upon loss of power, two limit switches, power on brake, stainless steel fasteners, 300 series stainless steel output drive, polyester powder coating.
