RF expansion valve

wide range of evaporation temperature; fixed valve inside and stable performance; one-direction refrigeration valve

Model RF Expansion Valve is a conventional themodynamic expansion valve.

Model RF Expansion Valve is used to regulate the liquid refrigerant supply in the evaporator.

Model RF Expansion Valve is particularly applicable to the supply of the liquid refrigerant in the dry evaporator.

Model RF Expansion Valve functions automatic control by the overheat degree of the refrigerant.
