MPK-15-5 Series 2

Function of MPK-15-5 Series 2

The main function of MPK-15-5 Series 2 is remote control of rotary actuating elements. The mechanism receives an electrical command and turns the output shaft to open, close or regulate the connected valve or damper. It can be used in fuel, air conditioning, ventilation, anti-icing and other systems where cockpit or automatic control is required. The built-in drive system converts motor rotation into controlled shaft movement, while the limited-travel design prevents unrestricted rotation of the connected equipment.

Two-motor design and torque limiting clutch

MPK-15-5 Series 2 is described as a two-motor mechanism using D-10ARU type electric motors. The two-motor layout allows normal and backup / emergency operation depending on the aircraft system logic. A friction torque-limiting clutch protects the mechanism and connected valve or shutter from overload at end positions or if the driven element jams. This construction is useful for aircraft systems where reliable actuation is required, but mechanical damage from excessive torque must be avoided.

Adjustable output shaft travel

The MPK-15-5 Series 2 mechanism has a limited and adjustable output shaft angle. In the supplied context, the working travel is described as adjustable by external rigid stops, with values from 25° to 95° for MPK-15-5 and up to 180° in broader MPK-15 references. For this reason, the exact required travel angle must be checked before replacement. During installation or maintenance, technicians should confirm end-stop adjustment, limit switch operation, travel time, shaft alignment and the condition of the connected valve or damper.

Aircraft application of MPK-15-5 Series 2

MPK-15-5 Series 2 is associated with several Soviet and Russian aircraft types. The supplied context identifies Tu-22M aircraft as one of the most known applications, especially in cabin air conditioning control and emergency air shut-off functions. It also mentions Il-76, Yak-40 and Mi-8 / Mi-17 / Mi-171 family helicopters in applications related to air lines, anti-icing systems, life-support systems, ventilation and fuel shut-off valves. Exact applicability must be confirmed through the aircraft equipment list and system documentation.

Identification and ordering of MPK-15-5 Series 2

Before ordering MPK-15-5 Series 2, the buyer should confirm the aircraft type, installation system, required shaft travel, connector type, motor configuration, condition and documentation set. It is also important to clarify whether the unit is required as a standalone electromechanism or together with a valve, damper or shut-off assembly. The mechanism may be needed for aircraft system repair, replacement of a failed valve actuator, overhaul stock or industrial equipment support. Product passport, year of manufacture, storage condition and test records should be checked before shipment.
