Sporlan 168070 QC-0 Red Cartridge

The Sporlan 168070 QC-0 Red Cartridge is a critical replacement component for Type Q and BQ thermostatic expansion valves (TXVs) utilized in diverse refrigeration and air conditioning systems. Engineered for precision flow regulation, this size 0 orifice cartridge features a distinct red color code for rapid field identification and capacity matching. Designed to manage specific tonnage requirements efficiently, the QC-0 cartridge provides a nominal capacity of 1/6 ton for R-12/R-404A and 1/3 ton for R-22 applications, ensuring stable superheat control across varying load conditions. For technicians performing TXV orifice replacement, this cartridge style allows for rapid system resizing or repair without removing the valve body from the refrigerant line, minimizing downtime. Its durable brass construction and optimized pin angle ensure consistent refrigerant flow control and pressure regulation in both high and low-temperature settings. By integrating this Sporlan expansion valve part into your service inventory, you maintain the ability to restore optimal thermal management to commercial and residential DX systems with professional-grade reliability.

Key Benefits

• Field Interchangeability: Dramatically simplifies refrigerant capacity adjustments by allowing for quick cartridge swaps while the valve body remains brazed in place.
• Visual Identification: The red color code provides a clear visual standard to prevent installation errors during high-pressure service calls.
• Universal Compatibility: Fully compatible with Sporlan Q, EQ, SQ, and BQ valve series, supporting a broad range of legacy and modern refrigerant types.
• Precision Metering: Optimized for stable TXV superheat management, reducing the risk of compressor slugging or evaporator starving.

Common Questions

What is the tonnage rating for the QC-0 Red Cartridge?
The QC-0 Red Cartridge is rated for approximately 1/3 ton on R-22 systems and 1/6 ton on R-12, R-134a, and R-404A systems. Always verify capacity using the specific refrigerant's pressure-temperature chart for your application.

Which valve bodies are compatible with the Sporlan 168070?
This cartridge is designed for use with Sporlan’s Type Q conventional port and Type BQ balanced port valve bodies. This includes SAE flare, extended ODF solder, and versions with internal or external strainers.

Does this cartridge require specific tools for installation?
Yes, technicians should use a 4mm Allen wrench or the specialized Sporlan blue plastic triangle tool (often provided with BQ kits) to secure the cartridge into the valve body to ensure a leak-free sit.
