Thermostatic Expansion Valves

The Ranco® CO Series Thermostatic Expansion Valves (TXV) are designed with a replaceable port component that allows changeability to the nominal capacity. The valve is used to adjust the refrigerant supply volume in the evaporator by sensing the superheat degree of the evaporator outlet through a thermal sensing bulb and external (internal) balance.

The Ranco® BD Series Thermostatic Expansion Valves (TXV) are designed to meet the bidirectional requirements for heat pump systems. This TXV is used to adjust the refrigerant supply volume in the evaporator by sensing the superheat degree of the evaporator outlet through a thermal sensing bulb and external (internal) balance.

The Ranco® CV series Thermostatic Expansion Valves (TXV) are designed with built-in check valves, eliminating the need for a separate check valve in the system. This TXV is used to adjust the refrigerant supply volume in the evaporator by sensing the superheat degree of the evaporator outlet through a thermal sensing bulb and external (internal) balance.

The Ranco® M Series Thermostatic Expansion Valves (TXV) are designed to meet the requirements of small refrigeration equipment. This TXV is used to adjust the refrigerant supply volume in the evaporator by sensing the superheat degree of the evaporator outlet through a thermal sensing bulb and external (internal) balance.
