SS-TV series bi-flow thermostatic expansion valves use advanced structure of bi-directional balanced port.
SS-TV bi-flow series 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.
