Sporlan 168307 BQC-B Cartridge

When you are servicing balanced port thermostatic expansion valves, the Sporlan 168307 BQC-B Cartridge is the industry standard for maintaining precise superheat control. This pink valve cartridge is specifically engineered for Sporlan BQ series valve bodies, providing a reliable solution for commercial refrigeration and air conditioning systems. By utilizing a balanced port design, the BQC-B cartridge compensates for varying head pressures and prevents fluid velocity from affecting the pin and port alignment. This ensures stable evaporator performance across a wide range of operating conditions, particularly in low-temperature applications ranging from 0°F down to -40°F. As a veteran-grade HVAC replacement part, it includes an identification tag and color-coding for rapid field verification, eliminating guesswork during TXV service and repair. This drop-in refrigeration valve component is essential for contractors looking to restore system efficiency without replacing the entire valve body.

Key Benefits:

• Optimized Refrigerant Flow: Provides precise thermostatic expansion valve (TXV) metering to maintain consistent superheat at the evaporator outlet.
• Balanced Port Performance: Neutralizes the effect of pressure imbalances, ensuring reliable operation during seasonal ambient temperature shifts.
• Fast Field Identification: Features a pink color code and physical ID tag for immediate capacity matching during HVAC maintenance.
• Durable Construction: Built with high-grade materials to resist corrosion and erosion in demanding commercial environments.
• Modular Repair: Allows for total internal restoration of the valve assembly without the need for unbrazing the original valve body.

Common Questions:

The Sporlan BQC-B is designed for BQ, EBQ, and SBQ series bodies that require an 'B' size capacity insert. Always verify your specific capacity requirements against the system's tonnage and refrigerant type before installation.

Sporlan uses color coding to signify specific orifice sizes and capacities. The pink designation ensures the technician is installing the correct balanced port cartridge for the intended cooling load, preventing hunting or floodback issues.

Yes, the 168307 BQC-B is highly effective in low-temperature settings, including commercial freezers and cold storage, where maintaining stable superheat at low suction pressures is critical.
