Operation
As the valve stem moves downward, the flow through the
NO port decreases and the flow through the NC port
increases. As the valve stem moves upward, the flow
through the NO port increases and the flow through the
NC port decreases.
In the event of power failure, a spring return actuator
returns the valve to its normal position. Non-spring return
actuators will hold the last commanded position. See the
Technical Instructions of the various actuators for
additional information.
