Question

When applied to a system with air cooled condensers, what is the lowest outside ambient temperature that balanced-port valves can typically work without head pressure control?

Answer 1

Balanced-port valves can typically work without head pressure control in low ambient temperatures down to approximately -20°C or -30°C.

Step-by-step explanation:

When applied to a system with air cooled condensers, the lowest outside ambient temperature that balanced-port valves can typically work without head pressure control depends on the specific design and manufacturer recommendations. However, as a general guideline, balanced-port valves are designed to work in low ambient temperatures down to approximately -20°C or -30°C without requiring head pressure control. It is important to consult the manufacturer's documentation and guidelines for the specific valves being used to determine the lowest temperature threshold without head pressure control.
