Models & Details for “Core-replaceable thermodynamic expansion valve”
It is used to adjust the amount of refrigerant liquid injected into the evaporator. The amount of injection is controlled by the superheat of the refrigerant, so it is particularly suitable for injecting into a dry evaporator because the superheat of its outlet refrigerant is proportional to its load. Interchangeable orifice assembly.
Our factory produces professional matching nozzle assembly (spool), complete model, reliable quality, welcome to purchase.
Evaporation temperature: -60 ° C ~ +10 ° C
Features:
△ Evaporation temperature range: -60 ° C ~ +10 ° C, can use for low-temperature freezing , refrigeration and air conditioning
△ Interchangeable orifice assembly: is easy to match stock and capacity to provide customers with better service
△Adjustable superheat: it can match all of the evaporator and give full play of the evaporator performance.
△ You can choose external pressure balance or internal pressure balance according to your need.
△ flare or welded connection.
