Chinese Thermostatic thermal expansion valve,Manufacturer, Supplier, Factory, Exporter in china
ST2,STE2 thermal expansion valve
Porduct Introduction
Thermostatic expansion valve regulate the flow rate of refrigerant into
evaporators according to its degree of superheat.
Both the iternal equalizer and external equalizer systems are furnished,
especially, the external equalizer type efficiently eliminates the
influence resulted from the loss od 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桫+10
