Sporlan 168306 BQC-A Cartridge

The Sporlan 168306, identified as the BQC-A Cartridge, is a critical component for maintaining precise refrigerant flow within Sporlan BQ Series thermostatic expansion valves (TEV). This blue-coded cartridge is engineered for balanced port expansion valves, specifically designed to handle systems with widely varying operating conditions, such as fluctuating head pressures or high pressure drops. As a TEV replacement part, the BQC-A size "A" provides a nominal capacity range suitable for air conditioning and commercial refrigeration applications (typically 3/4 to 1-1/2 tons depending on the refrigerant type). The BQC-A Blue Cartridge features a field-serviceable design that allows for rapid replacement without removing the valve body from the line, ensuring minimal system downtime. This kit includes the necessary identification tag to be wrapped around the capillary tubing, verifying the correct capacity and Sporlan valve cartridge selection for the specific HVACR service part requirement.

• System Versatility: Optimized for both air conditioning and low-temperature refrigeration applications using the balanced port design to mitigate pressure fluctuations.
• Precise Capacity Matching: The BQC-A size "A" provides consistent superheat control across a range of refrigerants, including R-22, R-410A, and R-404A.
• Easy Field Identification: Color-coded blue with an included cartridge identification tag to prevent sizing errors during service calls.
• Service Efficiency: Part of a three-piece valve assembly (body, element, and cartridge) that allows for the replacement expansion valve cartridge to be installed quickly using a standard BQ cartridge tool.
• Durable Construction: Built to Sporlan's rigorous industrial standards to withstand high-cycle environments in commercial systems.

Which valve bodies are compatible with the BQC-A cartridge?
This cartridge is specifically for use with the Sporlan BQ, SBQ, and EBQ series balanced port thermostatic expansion valves. It is not interchangeable with standard "Q" series cartridges.

How do I confirm the capacity of this cartridge for my specific refrigerant?
The "A" size designation corresponds to specific tonnage ratings based on the refrigerant used. For example, it is typically rated for 1 ton in R-134a systems and 1-1/2 tons in R-22 or R-410A systems. Always verify against the Sporlan capacity chart for your specific application.

Does the cartridge include the necessary seals?
Replacement cartridges generally require specific O-rings for a leak-proof seal. It is best practice to inspect and replace the cartridge O-rings whenever the valve is disassembled for service.
