Type SKD62U Electric Actuator
Principle of Operation
The actuator accepts a 0 to 10 Vdc, 0 to 135 or a 4
to 20 mA control signal. The actuator, mounted on
a valve, produces a stroke proportional to the input
signal. When power is turned off or the event of a
power failure, the actuator spring returns the valve to
its normal position.
