Sporlan 168304 BQC-AA Valve Cartridge

The Sporlan 168304 BQC-AA is a precision-engineered replaceable valve cartridge designed for use with Sporlan BQ series thermostatic expansion valves. Identified by its yellow color-coded tag, the BQC-AA provides reliable superheat control in light air conditioning and commercial refrigeration systems. This balanced port design cartridge compensates for fluctuating head pressures and varying evaporator loads, making it an essential component for maintaining system efficiency and preventing liquid floodback. The Sporlan 168304 is technically identical to the BQC-AA cartridge, featuring a robust internal construction that ensures accurate refrigerant metering across a wide range of operating conditions. For service technicians, utilizing this OEM replacement part ensures the TXV performance remains within factory specifications, simplifying field repairs and reducing the need for complete valve body replacements in R-22 and R-407A applications.

• Balanced port construction ignores high-pressure fluctuations for stable evaporator feeding.
• Color-coded identification allows for rapid field verification of cartridge capacity and application type.
• Drop-in compatibility with standard Sporlan BQ valve bodies facilitates faster service calls and reduced downtime.
• Removable design permits internal valve cleaning or capacity changes without de-brazing the liquid line connections.
• Enhanced modulating control improves overall thermal stability in systems with fluctuating ambient temperatures.

What refrigerant types is the BQC-AA cartridge compatible with?
The BQC-AA is typically used in R-22 and R-407A systems, though compatibility depends on the specific thermostatic charge and valve body configuration.

How do I identify the capacity of this cartridge in the field?
Look for the yellow tag attached to the cartridge; the BQC-AA designation specifically denotes the port sizing and capacity range within the BQ valve family.

Does this cartridge require specific tools for installation?
Standard HVAC refrigeration tools are sufficient, but ensure the valve body interior is free of debris and the O-rings are properly seated to prevent bypass leaks.
