Maximum efficiency over a wide temperature and load range
Stainless Steel versions available
Improved refrigerant returns to the compressor, assuring better cooling while reducing the possibility of liquid slugging, which can destroy the compressor.
Thermal Expansion Valves are a component in refrigeration and air conditioning systems that control the amount of refrigerant that flows into the evaporator, controlling the superheating at the outlet. To do this correctly, the valve needs to be selected to match the BTU capacity of the system’s evaporator and compressor.
We offer products with conventional and specialized designs, that when applied to systems will showcase the high-quality of the products that are designed for our customer’s precise needs. These expansion valves optimize the management of HVAC systems with a special focus on energy conservation.
The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator.
The high-pressure liquid refrigerant entering the expansion valve is quite warm. This may be verified by feeling the liquid line at its connection to the expansion valve. The liquid refrigerant leaving the expansion valve is quite cold. The orifice within the valve does not remove heat, but only reduces pressure. Heat molecules contained in the liquid refrigerant are thus allowed to spread as the refrigerant moves out of the orifice. Under a greatly reduced pressure the liquid refrigerant is at its coldest as it leaves the expansion valve and enters the evaporator.
The entire set of products are matched according to customer requirements, and small accessories are produced according to customer drawings
