effectively mitigating the risk of ice formation at the expansion valve and long-term copper plating on compressor internals

Its CWLE (Clockwise Lead End) rotation and sleeve bearing construction ensure balanced airflow and reliable heat dissipation from the refrigerant coils

Optimized Efficiency: Rated at 1/8HP and 1100 RPM to maintain original factory SEER ratings and cooling capacity

Simplified Installation: Designed for field-mount applications to streamline damper linkage synchronization

meaning the spring return mechanism will drive the valve to the fully open position if pneumatic pressure is lost
