Brass Valves

A brass valve in a split air conditioning system typically refers to:

Service valves (for refrigerant lines, usually suction and liquid line valves)

Made of brass for durability and corrosion resistance

Used during installation, servicing, or recharging refrigerant

Refrigerant Flow Control

It controls the flow of refrigerant between the indoor and outdoor units.

Used to isolate the indoor unit or outdoor unit for maintenance or repair.

Servicing and Charging Refrigerant

Has a Schrader port or similar access point where technicians can connect gauges or add/remove refrigerant.

System Pressure Testing

During installation, these valves allow pressurization of the system to check for leaks.

Vacuuming the Lines

Before charging with refrigerant, the valves are used to evacuate air and moisture from the copper lines.

Sealing the System

When the AC is not in use or being transported, valves can be closed to seal in the refrigerant gas.
