Application
These 12-inch actuators are designed to be used on Flowrite VF 599 Series valves in
liquid service and steam service.
Operation
The control air signal upon the diaphragm causes the valve to modulate whenever the air
pressure is within the spring range of the actuator. The actuator springs provide the
necessary force to hold the stem in the stem up (direct acting) position.
