OPERATION

In a direct-acting (n.o. valve) system, an increase in control (branch/pilot) air pressure forces the Actuator diaphragm and cup assembly downward, forcing the valve stem down to proportionally close off the flow through the valve (Fig. 1).

THERMOSTAT

POSITIONER

In a reverse-acting control (branch/pilot) air pressure forces the Actuator diaphragm and cup assembly upwards, forcing the valve stem up to proportionally increase the flow through the valve.

In Actuators without Gradutrol Relays or positive

positioners, branchline pressure is applied to the diaphragm. In Actuators with Gradutrol Relays or positive positioners, up to full main air pressure is applied to the diaphragm to ensure the valve is positioned proportionally

to the pilot pressure (the branchline pressure output from

the controlling device).
