@refrigerationmentor: How do you explain the stepping action inside an EEV to someone learning refrigeration? Drop your explanation in the comments. This clip shows how a six-wire EEV uses electrical pulses to rotate its internal magnet and drive the valve pin. Seeing the teeth, coils, and magnetic poles in action helps technicians understand how precise refrigerant metering is achieved. • 12-volt pulse demonstration • About 250 steps from closed to open • Each pulse energizes a coil • Alternating magnetic poles create rotation • Pin moves up or down based on stepping • Stepper-style control for accurate modulation Understanding how EEVs operate internally allows technicians to become better troubleshooters and system problem solvers. 👉 Follow us and check out our Refrigeration Mentor community where our technical specialists help uplift technicians and the industry.
