Precise flow regulation for efficient and reliable operation

Our series of electric expansion valves, ETS, offer you efficient and reliable operation, covering any air conditioning system demand. The valves are compatible with controllers from Danfoss as well as other manufacturers.

When matched with the Danfoss superheat controller, and pressure and temperature sensors, the valves are designed for precise liquid injection in evaporators. The valve is fully balanced, providing a bi-flow feature as well as solenoid tight shut-off function in both flow directions. The valve design uses a bipolar motor to provide precise flow regulation.
