Thermal Bi-flow expansion valve SS-TV series bi-flow thermoatatic expansion valve uses advanced structure of bi-directional balanced port. Bi-flow series thermostaticexpansion valve can be used in heat pumps, air conditions, refrigeration, liquid cooling, ice makers, bus refrigeration equipments and etc. The application of dual headpiece thermostatic expansion valve makes the refrigeration system need fewer amounts of expansion valves, check valves and solenoid valves.
