Temperature Responsive Electronic Expansion Valve



Product Description:

Electronic expansion valves are specifically designed for use in air conditioning and refrigeration systems or heat pumps. These valves offer automatic adjustment of the refrigerant flow rate, ensuring the system operates under optimal conditions for fast cooling or heating, precise temperature control, and energy efficiency. Additionally, they can be used for suction line pressure control. The bidirectional operation allows for effective refrigerant flow control in both heating and cooling modes.
