Sporlan 168303 BQC-AAA Cartridge

The Sporlan 168303 BQC-AAA Cartridge is a field-replaceable internal component engineered for Type BQ Balanced Port TEV bodies. As a veteran-grade refrigerant flow control solution, this AAA-sized red cartridge is designed to maintain precise superheat at the evaporator outlet, ensuring maximum heat transfer efficiency while preventing liquid slugging in the compressor. The balanced port design allows the BQC-AAA to mitigate the effects of varying head pressures, making it a critical choice for systems utilizing R-410A, R-404A, R-134a, and R-22. This specific AAA capacity cartridge is rated for 1/8 to 1/3 tons (R-22/R-410A) and includes the corresponding red identification tag to prevent mix-ups during high-volume service calls. Built with a brass body and stainless steel internal components, it provides the pin and port alignment necessary to withstand the high-temperature and low-temperature refrigeration cycles found in commercial food service and light commercial DX systems.

• Optimized Compatibility: Designed for seamless integration with Sporlan 3-piece Q and BQ thermostatic expansion valves.
• Red Capacity ID Tag: Prevents installation errors by providing immediate visual identification of the AAA nominal capacity.
• Pressure Stability: Characterized by balanced port geometry to ensure consistent performance across fluctuating ambient conditions.
• System Versatility: Suitable for multi-refrigerant applications including high-pressure R-410A and low-temp R-404A refrigeration.
• Field Serviceable: Minimizes downtime by allowing for direct cartridge replacement without removing the valve body from the liquid line.

Which valve bodies are compatible with the BQC-AAA?
The BQC-AAA is specifically for use with Sporlan’s 3-piece valve series, including the Type BQ (balanced port) and Type Q (conventional port) brass bodies.

What does the "AAA" size signify in this Sporlan cartridge?
The AAA designation indicates the smallest port size in the BQ series, typically handling loads between 1/8 and 1/3 tons depending on the specific refrigerant and liquid temperature.

Does this cartridge include the thermostatic element?
No, the 168303 is the internal cartridge and identification tag only. The brass body and thermostatic power element must be sourced separately for a complete valve assembly.
