Lochinvar & A.O. Smith 100208410 Rotor 318973-401 This ensures the pressure differential

This ensures the pressure differential at the TEV remains high enough to feed the evaporator properly

The P20CA-75 is technically identical to the P20CA-75C

The stem up open (UO) configuration and two-way valve body design facilitate streamlined performance when paired with compatible actuators for two-position or floating control

For high-resistance liquids like ultra-pure or distilled water

making it suitable for a wide range of heating elements
