Electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications.
The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions.
The valve design uses bipolar drive providing very precise flow regulation.
