Electronic Throttle Valve

In September 2016, Thermo King announced that a new Electronic Throttling Valve (ETV) is available for truck and trailer units, which utilise the older ETV.

The corporation promise that the new ETV do not have impact on the reliability, function or performance of the unit. The only noticeable change is on the ETV body , which only visible when the service door is opened. 

The new ETV has a change in the design of the valve body, motor actuator and cartridge. The new ETV also has an integrated Deutsch connector located on the top of the valve (no harness). The cartridge insert design allows for ease of service and low torque setting, providing low strain to piping during service and repair work.
