3.3 Inverted Valve Function
Fig.4: Function
NC: Actuator type normally closed
NO: Valve type normally open
For an inverted single-seat valve it should be noted that, compared with a
standard single-seat valve, the direction of action of an actuator will produce
exactly the reverse effect when the same amount of force is applied.
Example:
An actuator with NC action
• closes a standard valve (NC valve) by spring force
•
opens an inverted valve (NO valve) by spring force
