Spence Engineering TA120220 Thermo Assembly Els PW 29614 the Watts 740 series utilizes

the Watts 740 series utilizes non-metallic disc-to-metal seating and a stainless steel spring to resist corrosive water conditions and prevent "sticking" or freezing

eliminating the need for mounting bracket modifications or electrical lead splicing commonly associated with universal aftermarket motors

This 115/230V compatible motor (verified at 200-230V range) utilizes a 2-speed 1075/1080 RPM configuration for precise airflow control and features an Open Air Over (OAO) enclosure to maximize thermal dissipation during peak cycles

For critical industrial and HVACR applications
