Product Description
The EFS is an electric quarter turn spring return actuator which has the purpose to close or open a valve in emergency conditions, when an ESD alarm signal occurs or when motor power supply fails.
The EFS actuator consists of four main parts:
a spring return mechanism, which move the valve in the foreseen fail-safe condition when requested by an ESD signal or by a power failure.
a quarter turn electric actuator which operates the valve during normal working conditions.
an electro-magnetic clutch which hold in position an epicyclical gearing during the normal operation and release it in case of fail-safe function.
an oil damper, which is necessary to adjust the fail-safe speed and to manually operate the actuator by means of an hand-pump in case of power failure.
