Description

. . . . . The Johnson Controls D-251-405 is a pneumatic damper actuator from the D-251 Series with an 8-13 PSI spring range. Control air pressure from a pneumatic thermostat or controller acts on the actuator's diaphragm and drives the piston against the calibrated spring, positioning a damper in proportion to the signal - the standard method of damper control in pneumatic HVAC systems.

The spring range is the key selection detail on a pneumatic actuator: it sets the control pressure band over which the actuator strokes from fully closed to fully open. An 8-13 PSI actuator begins to move at 8 PSI and reaches full stroke at 13 PSI, which allows it to be sequenced with other actuators on the same control signal - for example running a heating valve on a low range and a cooling valve or damper on a higher range from a single thermostat output. D-251 actuators are supplied in four sizes (No. 2, No. 3, No. 4 and No. 6), and Johnson Controls supports the series with size-specific replacement diaphragms, connection heads and clevis pins; the later D-4073 actuator is described as a functional replacement for former D-251 actuators.
