Electric Expansion Valve

Solenoid type electric expansion valve

• Solenoid type electric expansion valve for car air conditioning system.
• Solenoid type valves are smaller and lighter than stepping motor type valves, and have faster response time for valve opening and closing.
• By using a bellows, the valve opening can be controlled corresponding to the current applied to the solenoid without being affected by pressure.

Feature

The solenoid type electric expansion valve has been developed for heat management systems such as heat pump systems.
It was developed by combining our solenoid valve and bellows technologies, which have been well proven in the market.
By using a solenoid system, the valve is smaller, lighter, and opens and closes faster, i.e., more responsive, than stepping motor systems.
In addition, the use of a bellows cancels the force to the valve parts by pressure, therefore the valve opening can be controlled corresponding to the current applied to the solenoid without being affected by pressure.
