MPK-13VTV

Control function of MPK-13VTV

The main function of MPK-13VTV is to rotate a connected valve or shutter within a preset angular range. The mechanism can be controlled manually by the crew or automatically by onboard temperature regulation and control systems. In air conditioning systems, this allows the aircraft to regulate air supply and distribution to cabins or compartments. The output shaft angle can be adjusted within the mechanism’s permitted range, allowing the unit to work with different shutter settings and installation requirements.

MPK-13VTV in aircraft air distribution systems

MPK-13VTV is used in air supply and distribution lines of aircraft air conditioning systems. In the Il-76 context, the mechanism is referenced as installed on shut-off shutter type 5419T. This shutter controls the flow of hot or cooled air to the left pressurization duct of the cargo cabin. The electromechanism therefore works as an actuator in the air management system rather than as an independent aircraft control unit. Exact installation should be confirmed by the aircraft maintenance and system documentation.

Limit switches and end-position protection

The MPK-13VTV mechanism includes built-in microswitches used as limit switches. They automatically disconnect power from the electric motor when the output shaft reaches the set end positions, such as “Open” or “Closed”. This protects the actuator, shutter and transmission elements from overload or overtravel. During maintenance, technicians should check limit switch operation, correct angular adjustment, output shaft movement, connector condition and proper actuation of the controlled valve or shutter.

Electrical and mechanical operation of MPK-13VTV

The mechanism operates from a 27 V DC aircraft power supply. According to the source context, the nominal output torque is 60 kgf·cm, while current consumption is around 1.0 A and may rise up to 1.7 A under maximum operating conditions. The actuator has a compact housing and an output shaft travel range adjustable from 30° to 180°. These characteristics make the unit suitable for limited-angle actuation where a controlled duct shutter or valve must be moved and held in position.

Identification and ordering of MPK-13VTV

Before ordering MPK-13VTV, the aircraft type, installation position, shutter type, required execution and documentation set should be confirmed. It is also useful to clarify whether interchangeability with MPK-13BTV or MPK-13DTV is allowed by the customer’s documentation. The unit may be required for air conditioning system repair, shutter actuator replacement, Il-76 maintenance or spare parts stock. Passport, overhaul status, inspection records, connector configuration and test results should be agreed before shipment.
