MPK-13DTV

Control function of MPK-13DTV

The main function of MPK-13DTV is to move a connected shutter or valve through a defined angular range. The actuator supports intermediate positioning as well as movement between end positions, depending on system design. It may be controlled remotely by the crew or automatically by onboard control units. In aircraft air systems, this allows regulation of hot and cold air flow, air distribution between compartments, or closure of a duct line. Correct operation of the mechanism is important for stable system control and predictable movement of the linked valve.

MPK-13DTV in aircraft air systems

MPK-13DTV is mainly associated with aircraft air conditioning systems, automatic pressure regulation systems and anti-icing systems. In air conditioning, it can control shutters that mix and distribute hot and cold air to the cockpit, passenger cabin or technical compartments. In pressure regulation systems, it may actuate valves involved in maintaining cabin pressure. In anti-icing systems, it can control shut-off valves supplying hot air to wings, slats, air intakes or other heated sections, depending on aircraft configuration and documentation.

MPK-13DTV with 4237BT, 4237D and 5403T shutters

The MPK-13DTV electromechanism may be installed on regulating air shutters and related actuated assemblies. The source context mentions use with shutter types 4237BT ps, 4237D and 5403T. In this role, the actuator is rigidly mounted to the shutter or valve body and rotates the control shaft through its limited angular travel. Since shutter variants and mounting arrangements can differ, the exact mating part, mounting dimensions, shaft orientation and connector configuration should be checked before replacement or supply.

Electrical and mechanical operation of MPK-13DTV

The mechanism operates from a 27 V DC aircraft power supply. According to the supplied data, the output opposing torque is 9.8 N·m, or 100 kgf·cm, and the current consumption is not more than 0.46 A. The output shaft travel is adjustable from 30° to 180°, while a full 180° rotation takes 48 to 72 seconds. This slow movement is suitable for air-system regulation, where smooth controlled positioning is more important than high-speed actuation. The operating mode is repeated short-time operation.

Identification and ordering of MPK-13DTV

Before ordering MPK-13DTV, the aircraft type, installation system, actuator execution and connected shutter or valve should be confirmed. It is important to specify whether the actuator is required separately or in assembly with an air shutter, such as 4237BT ps. The buyer should also clarify documentation requirements, condition category, overhaul status, connector configuration and mounting requirements. The unit may be required for repair of air conditioning systems, pressure regulation systems, anti-icing valves or spare parts stock for Soviet / Russian aircraft and helicopters.
