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

Industrial Construction: High-grade cast iron provides the heat dissipation and structural integrity needed for continuous operation

It features a 3/4" NPT connection and is specifically calibrated for a high-pressure opening point range of 145 to 190 PSI

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

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