Low Price Automatic Thermal Expansion Valve (STDE)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: -40º C-+10º C
