PNEUMATIC DAMPER ACTUATOR 8-13 Spri

MK-3121 Pneumatic Damper Actuator 8-13 Spri.

SCHNEIDER ELECTRIC MK-3121 Pneumatic Damper Actuator 8 to 13 psi   is a pneumatic damper actuator that controls damper rod positions and duct blower dampers in range of 8-13 psi, while providing precise control. It comes with a 45 deg. fixed trunion or duct plate, a closed face triangle handle without holes, and non-roller cam.

The MK-3121 Pneumatic Damper Actuator allows for the speed and convenience of pneumatic control of smaller shafts. It features a 4-way and 8-13 split proportional actuator as well as field selectable non-proportional flow ratios and variable porting for applications requiring multiple flow paths. This unit is designed for use with a manual spring return or optional electric reversion. Various mounting brackets and view ports are available to meet various customer requirements.

The Schneider Electric MK-3121 damper actuator is used in 1"-13 Spline Applications. A pneumatic actuator is a pneumatically operated device to convert electrical energy into mechanical energy, particularly for moving and controlling of valves.

This 8-13 speed, 120/240 VAC (50-60Hz) pneumatic Activator has a speed range of .06 - 12 cycles per minute. This unloader initiates starting current, compensates for differential pressure drops and reduces superheat in the coil or evaporator.

The Schneider Electric 2-Pole MK-3121 Pneumatic Damper Actuator with lever handle enables energy saving and ventilation of your room. With external open/close position indicator, this actuator features a minimum throw of 6 mm and a maximum throw of 550 mm. Easily install with 5 terminals, this actuator can be used to control the dampers in residential or industrial venting projects.

The MK-3121 Pneumatic Damper Actuator provides smooth and quiet operation, low energy consumption, infinite adjustability/range plus proprietary integrated motorized damper actuators. The design is NEMA 4X / IP66 rated and UL Listed for dry and damp locations. The MK-3121 incorporates a micro-electronics module able to adjust the speed of the opening/closing motion and also an integral over-temperature safety control.
