Product Description:
The Refrigeration Type R134A Electronic Expansion Valve is designed for use in air conditioning and refrigeration systems or heat pumps. This valve allows for automatic adjustment of the refrigerant flow rate, ensuring optimal system performance for fast cooling or heating, precise temperature control, and energy efficiency. It can also be used for suction line pressure control. The bidirectional operation enables it to regulate refrigerant flow in both heating and cooling modes.
Key Features:
- Designed for oil-free systems (T series)
- Compact design with low height, small volume, and lightweight
- Optimized flow path for noise reduction
- Fast response and energy-saving performance
- Compatible with reversible systems such as heat pumps, supporting bidirectional flow
