MPK-13BTV

MPK-13BTV rotary aircraft electromechanism

MPK-13BTV is an aviation rotary electromechanism with limited output shaft travel. It is used in onboard aircraft systems for remote control of air shutters, mixing valves and distribution valves. The unit is associated with air conditioning and anti-icing systems, where controlled movement of a valve or shutter is required. In aircraft such as the An-26, MPK-13BTV may be installed in engine nacelle areas and connected mechanically to the drive shaft of a mixing valve.

Control function of MPK-13BTV

The main function of MPK-13BTV is controlled rotation of a connected valve or shutter. The mechanism receives electrical control signals from aircraft control units and moves the output shaft within a limited angular range. This allows the system to adjust the position of air-mixing or distribution elements. In air conditioning systems, this movement helps regulate the mixture of hot and cold air. In anti-icing installations, the mechanism may be used to control hot-air supply paths, depending on aircraft configuration and documentation.

MPK-13BTV in aircraft air conditioning systems

In the An-26 system context, MPK-13BTV is linked with the aircraft air conditioning system. The mechanism can be mounted on the lower engine nacelle cowling cover near the AI-24VT turboprop engine and connected to the mixing valve drive shaft. Control commands may be supplied from cockpit controls and temperature automation units. The actuator adjusts the valve position according to manual or automatic commands, supporting air temperature regulation in the crew cabin or other conditioned compartments.

Limit switches and position feedback

MPK-13BTV includes internal limit switches that disconnect motor power when the driven valve reaches its end positions. This protects the mechanism and linked shutter from overtravel in the “Open” and “Closed” directions. The unit also provides position feedback signals to associated cockpit controls and equipment. This feedback allows the crew or automatic control system to monitor the current position of the controlled valve or shutter. Exact signal routing and connector pinout should be confirmed through aircraft wiring diagrams.

Drive and electrical operation of MPK-13BTV

The mechanism operates from the aircraft DC electrical network. According to the source context, the nominal supply is 27 V DC and the current consumption is approximately 1.0 to 1.7 A, depending on operating load and execution. The electromechanism works with a DC motor, such as a D-1.6 series motor in referenced configurations. Output shaft travel may be adjusted depending on modification and valve setting. During maintenance, technicians should check motor operation, limit switches, output shaft travel, connector condition and feedback signal.

Identification and ordering of MPK-13BTV

Before ordering MPK-13BTV, the aircraft type, installation system, required execution and documentation set should be confirmed. It is useful to specify whether interchangeability with MPK-13VTV or MPK-13DTV is acceptable under the customer’s documentation. The unit may be required for air conditioning system repair, anti-icing valve control, engine nacelle maintenance or spare parts stock. Product passport, overhaul status, inspection records, connector configuration and operating test results should be agreed before shipment.
