The at rest position of the valve, although normally closed (down position), can also be provided in the normally open (up position), this is determined by the actuator mode being either Spring Extend (SE) or Spring Retract (SR) as selected at time of order.
The mode can also be easily changed on site by simply inverting the actuator assembly. When air pressure is applied to the cylinder, the valve plug moves through its entire stroke changing from one state to the other. In the case of the F267J+ from open to closed or vice a versa, and the F268J+ changing the flow path from one direction to the other.
