simplifying the replacement of legacy proportional valve actuators

Symptoms typically include the outdoor coil becoming a solid block of ice or the system cycling into defrost mode when no frost is present

extending the operational life of the blower motor and drive components

it initiates a circuit break if temperatures exceed the factory-defined threshold

Why did my original PTCR fail

Watts 2065501 Orifice Assembly 323613-751 simplifying the replacement of legacyThe Watts 2065501 Fixed Orifice Assembly is a critical component for technicians requiring exact fluid and gas flow management within commercial and industrial hydronic environments. Designed for stationary flow regulation, this fixed orifice opening eliminates the variables associated with adjustable valves, ensuring a constant discharge coefficient for HVAC, chemical processing, and manufacturing systems.
