Control Devicesfor Automobiles

Thermostatic expansion valves

Thermostatic expansion valves

These devices ensure that cabin comfort is efficiently maintained by adjusting the refrigerant flow volume with reference to cabin temperature and other factors.

Compressor control valves

Compressor control valves

These devices control the discharge capacity of the compressor, suppress temperature fluctuations, and lighten the load on the compressor.
We offer both mechanical and external compressor valves.

Motor actuators

Motor actuators

In addition to allowing the switching of air flow between vents and internal/external ventilation, these devices trigger dampers that adjust air temperature.

Solenoid valves for hybrid / electric car

Solenoid valves for hybrid / electric car

This valve is mounted on heat pump car A/C to be used for switching refrigerant flow depending on A/C mode of cooling / heating.

Combination valves

Combination valves

This is a control valve integrated with thermostatic expansion valve and 2-way solenoid valve (to stop / flow refrigerant).

Pressure switches

Pressure switches

These switches activate/deactivate compressors or condenser fans depending on refrigerant pressure.

Fuel control devices

Fuel control devices

These devices are solenoid valves that control supply of fuel to diesel engines.

Anti-fog humidity sensors

Anti-fog humidity sensors

These sensors detect fog on window glass and relay relevant data to air conditioner controls.

Temperature and humidity sensors

Temperature and humidity sensors

These sensors detect the cabin temperature and humidity and relay relevant data to air conditioner controls.

Sunlight sensors

Sunlight sensors

These sensors detect the intensity of sunlight hitting the vehicle and relay relevant data to air conditioner controls.

Hot-water control valves

Hot-water control valves

These devices control hot-water flow to heat exchangers (heater cores) and adjust the temperature of air discharged.

Vacuum actuators

Vacuum actuators

These devices are powered by negative pressure by engine and control accelerator stroke.
