MPK-14MTV Series 2

MPK-14MTV Series 2 rotary electromechanism

MPK-14MTV Series 2 is an aviation electromechanical actuator of rotary action with a limited shaft rotation angle. The unit is used for remote movement of air dampers, valves and other controlled elements in aircraft ventilation, heating and air conditioning systems. In the supplied context, the mechanism is associated with Mi-26 helicopters and other aviation equipment where compact electric rotary drives are required. The actuator receives electrical commands from the aircraft control circuit and mechanically positions the connected damper or valve.

Function of MPK-14MTV in aircraft air systems

The main function of MPK-14MTV Series 2 is automatic opening, closing or positioning of air-flow control elements. It can be installed in air supply, mixing and distribution circuits where dampers regulate the flow of hot, cold or conditioned air. The mechanism allows the crew or automatic control system to move a damper without direct mechanical linkage from the cockpit. Correct operation of the actuator is important for maintaining normal air distribution, cabin ventilation and heating / cooling control.

Application on Mi-26 helicopters

MPK-14MTV Series 2 is referenced in the context of civil and military Mi-26 helicopters. Inside the aircraft, it may be used in the air conditioning system, heating system and ventilation system, depending on configuration and documentation. The mechanism may be mechanically connected to rotary dampers or valves installed in air ducts, including air supply lines from engines or the auxiliary power unit according to system layout. In some configurations, similar MPK-series drives may also be used with intake dampers or anti-icing related air-control elements.

Rotary actuator construction

The MPK-14MTV Series 2 mechanism includes a compact electric motor, reduction gearbox, output shaft, limit-switch arrangement and aviation plug connector. The gearbox converts motor rotation into controlled low-speed torque at the output shaft. Limit switches restrict movement at the end positions and prevent overtravel beyond the permitted shaft angle. The actuator is integrated into the aircraft electrical system through its connector and is mounted near the damper, valve or controlled air-system element.

Operating characteristics of MPK-14MTV Series 2

The actuator operates from a 27 V DC aircraft power supply and provides a limited rotary movement of the output shaft. According to the supplied context, the nominal output torque is 5 kgf·cm, with current consumption not exceeding 0.43 A. The shaft rotation angle is 100°. These values make the unit suitable for small air-control elements where precise end-position movement is required rather than continuous rotation. The mechanism is designed for aircraft vibration, temperature variation and pressure-change conditions.

Identification and ordering of MPK-14MTV

Before ordering MPK-14MTV Series 2, the aircraft type, exact installation point, controlled damper / valve and documentation requirements should be confirmed. It is also important to clarify whether the customer needs a new current-production unit, first-category stored item, overhauled unit or serviceable actuator. The product may be required for air conditioning system repair, ventilation control troubleshooting, heating system maintenance or spare parts stock for Mi-26 equipment. Product passport, test records and manufacturer acceptance documents should be agreed before shipment.
