Danfoss, Alco, Sanhua thermostatic valves and Alco-Emerson thermostatic bodies. A thermostatic valve has the role of controlling the flow of refrigerant within the refrigeration or air conditioning system by the ...fact that the climate expansion valve or the refrigeration thermostatic valve facilitates the change of the pressure of the liquid freon in the aggregate with the refrigerant in the form of gas and with low pressure within the internal unit . A thermostatic valve is a device capable of working well when the load fluctuates and is therefore very suitable for use in the air conditioning system (air conditioning expansion valve). When the evaporator heats up, the expansion valve ensures a higher flow and when it cools down, the exoansion valve reduces the flow. When you want to select the right product, it is essential to consider the freon used, the weldable or threaded connections of an air conditioning or refrigeration expansion valve, the diameters of the connections, equalization and the maximum operating pressure (MOP) of the expansion valve you are looking for.
