Thermostatic expansion valve is a kind of interchangeable orifice valve, which automatically monitors the flow rate of refrigerant according to its degree of superheat at the outlet of evaporator. It can fill in various kinds of refrigerant as customers' request, and be widely used in refrigeration cabinet, ice maker, dehumidity unit and other refrigeration units.
Specifications
Thermostatic expansion valve regulate the flow rate of refrigerant into evaporators according to its degree of superheat.
Product Introduction
Thermostatic expansion valve regulate the flow rate of refrigerant into evaporators according to its degree of superheat.
Both the internal equalizer and external equalizer systems are furnished, especially, the external equalizer type efficiently eliminates the influence resulted from the loss evaporator pressure.
The interchangeable orifice is easy to store and maintain, making the equipment to match with the system with ease.
Wide range of evaporator temperature: -40° C~+10° C
Packaging & Delivery
Packaging Details: Each products packed in small single box, then packed in big carton box.
Delivery Detail: 20-25 Days
