RB9 Series Multi-Function
Heat-Pump Flare Valves
Parker’s RB9 Multi-Function Flare Valves are used as
service valves in mini-split heat pumps. The valves
isolate sections of a system for servicing and provide
a means for charging refrigerant into a unit. The valve
also holds a restrictor and screen to meter refrigerant
and filter debris, increasing system efficiency.
Application
• Mini-split heat pumps
Base Product Part Number
RB9
Features and Benefits
• Inclusion of a restrictor into the valve provides
precise refrigerant metering to increase efficiency.
• Noise and vibration through the unit are reduced
by inclusion of the restrictor into the valve.
• Inclusion of a screen into the valve filters dirt and
debris prior to entering the restrictor, maintaining
full flow and enhancing performance.
• Captivated stem-design holds the stem within
the valve to prevent it from releasing when the
cap is removed or the unit is serviced, reducing
the potential for injury.
• Combined functionality of valve, restrictor, and
screen reduces component inventory (shut-off
valve, field-access gage port, expansion device,
filter screen or strainer, line-set connector, check
valve, by-pass circuit, and capillary tubes) leading
to a reduction in overall installed cost.
• Combined functionality of valve, restrictor, and
screen also reduces space requirements within
a unit and eliminates braze joints to reduce
potential leaks paths.
• Patent-pending.
