5350T.010

5350T.010 System Overview

The 5350T.010 is an aircraft thermostatic valve designed for operation within engine oil systems and used as part of radiator assembly 5349T on helicopter platforms.

5350T.010 Control Function

The valve performs automatic temperature regulation of the working fluid by redistributing flow between the bypass line and the cooling radiator, ensuring stable thermal conditions of the engine oil system during operation.

5350T.010 Aircraft Application

The unit is applied in helicopter powerplant systems, including Mi-8MTV, Mi-17, and Mi-24, and is used in conjunction with engines of the TV3-117 family as part of oil cooling and circulation systems.

5350T.010 System Integration

The valve is installed in the oil line between the engine and the oil radiator, directing fluid flow depending on temperature conditions to support efficient warm-up and cooling processes. The product is also known under alternative designation 5350T.010.
