Sporlan 168072 QC-1 Yellow Cartridge

When you're servicing Type Q or BQ thermostatic expansion valves, the Sporlan 168072—also identified as the QC-1 Yellow Cartridge—is the specific internal component required for precise refrigerant metering. This yellow valve cartridge is engineered for a conventional port TEV and is critical for maintaining accurate superheat control in commercial refrigeration and air conditioning systems. The Sporlan QC-1 features a replaceable design that allows for rapid field service without de-brazing the entire valve body from the liquid line. It is optimized for HVACR service parts applications involving R-22 and R-404A, supporting capacities of 1/2 to 3/4 tons depending on the refrigerant and evaporator temperature. Each 168072 unit includes a metal I.D. tag for permanent identification on the capillary tubing, ensuring that future technicians can quickly verify the Sporlan 168072 QC-1 orifice size and system compatibility during routine maintenance or performance troubleshooting.

Key Benefits

• Internal Portability: The Sporlan QC-1 yellow cartridge allows for quick capacity changes or orifice cleaning without removing the valve body, reducing downtime.
• Precision Metering: Designed specifically for the Type Q conventional port, ensuring stable performance across medium to high-pressure refrigeration cycles.
• Permanent Identification: Includes a durable I.D tag that wraps around the capillary tube to prevent confusion during multi-cartridge system repairs.
• Interchangeable Design: Fully compatible with both 168072 and QC-1 part numbers, providing flexible sourcing for technical inventory.

Common Questions

Does this cartridge work with balanced port valves?
The Sporlan 168072 QC-1 is designed for conventional port Q series valves. For balanced port applications, you should utilize the BQC series cartridges to ensure proper pressure equalization.

How do I identify the capacity of this cartridge in the field?
The top surface of the QC-1 yellow cartridge is color-coded yellow, and the specific capacity code is stamped directly on the component and the included I.D. tag.

What tools are required for installation?
Installation into a Sporlan Q valve body typically requires a 4mm Allen wrench to secure the cartridge into the brass housing after ensuring the O-rings are properly seated.
