SCHNEIDER ELECTRIC 30113 (Barber Colman) MK-7121 "8-13#DAMPER ACT

PROPORTIONAL PNEUMATIC DAMPER ACTUATOR 8-13 OPERAT

The 8-13#DAMPER ACTUATOR from BARRON Colman is a proportional pneumatic damper actuator. The damper is designed to provide positive proportional control of flow on centrifugal and mixed flow fans. It is ideal for use with fans such as the VARGET, VMAX, and V28. This type of damper can be used with a wide range of gas pressures, depending on…

The MK-7121 (8-13#) is a Proportional Pneumatic Actuator that provides up to 1000 lb. of force to an 8" or 13" damper assembly. Its 1/2 HP, 2-wire direct drive motor is powered by 115 volt AC single phase power through a built in wave form sensor with auto reset. This product is suitable for B, C, E HVAC systems and vertical applications.

The MK-7121 proportional pneumatic damper actuator is used in balancing, damping, position, control and tuning applications.

Dynamic stiction is a common problem in mechanical devices. To solve this issue, achieve dynamic movement with the MK-813 proportional pneumatic damper actuator that's been designed to be insensitive to air pressure fluctuations. Featuring high frequency operation, this damper's temperature coefficient has been designed to exceed the 0.3% level and its non proportional element has been optimized to minimize transient and steady state errors. It's built with an output that's virtually constant within less than 1% of the setpoint even for small changes in process conditions or varying loads.

The Mk 7121 is a proportional pneumatic damper actuator that controls airflow to the heating or air conditioning systems in buildings. The damper is positioned by a magnetic sensing element that activates a precision damping mechanism. The position of the damping mechanism controls the speed at which the damper moves, which, in turn, controls the airflow to the system.

This Schneider Electric 30113 (Barber Colman) MK-7121 pneumatic damper actuator is a proportional valve that controls dampers by changing the pressure in the air line to the damper. This proportional valve utilizes a latching solenoid valve, barometric discharge to sense pressure changes in the air supply and a Control Unit. It features automatic resetting when power is lost and 2 sets of contacts are included.

The MK-7121 Series with pneumatic air is a proportional type of hydraulic damper actuator using MK series, which replaces the typical hydraulic actuators and uses compressed air to work. It can be used in place of pneumatic control valves on the piping of the plant.
