Description
The SS-TV series of bi-flow thermostatic expansion valves utilize an advanced design of a bi-directional balanced port. These thermostatic expansion valves are widely used in heat pumps, air conditioners, refrigeration, liquid cooling, ice makers and more.

The application of a dual headpiece thermostatic expansion valve ensures the refrigeration system requires fewer expansion valves, check valves and solenoid valves.
