Spring Return Actuators - Model ES2Model ES@ 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... (read more)Browse Electric Valve Actuators Datasheets for Indelac Controls, Inc. -
