Sporlan 168078 Pink Q Cartridge

The Sporlan 168078, also known by technicians as the QC-4 Pink Q Cartridge, is a high-precision, replaceable cartridge designed for use with Type Q and BQ thermostatic expansion valves. This specific Pink color-coded orifice is critical for achieving accurate refrigerant metering in small to medium refrigeration systems, providing a nominal capacity of approximately 2 to 2.5 tons when used with R-22, depending on evaporator temperatures and pressure drops. As a veteran-preferred HVACR service part, the QC-4 is identical to the 168078 and includes the necessary ID Tag to ensure clear identification of the valve's capacity once installed. Its drop-in design allows for rapid field replacement without necessitating the removal of the TEV valve body, significantly reducing labor time during service calls. Developed for reliability in both air conditioning and commercial refrigeration, this Sporlan expansion valve cartridge ensures stable superheat control by utilizing a port design that optimizes flow even at light loads.

• Interchangeable Design: Perfectly compatible with standard Sporlan Q and BQ series brass bodies, allowing for easy capacity adjustments in the field.
• Technical Identification: The Pink ID Tag wraps securely around the capillary tube to prevent future guesswork regarding valve sizing and capacity.
• High-Performance Metering: Specifically engineered to minimize energy losses and improve overall system efficiency through precise refrigerant flow regulation.
• Durable Construction: Features robust internal components designed to withstand the rigors of high and low-temperature refrigeration environments.

Is the 168078 compatible with R-410A systems?
Yes, the QC-4 cartridge can be used in R-410A applications, though capacities will differ from R-22 ratings. Always consult the Sporlan capacity chart to ensure the orifice size matches your system's BTU requirements under varying liquid temperatures.

How do I install the QC-4 cartridge update?
The cartridge seats into the valve body using a 4mm Allen wrench. Ensure the O-rings are lubricated with high-quality refrigeration oil before seating to prevent leaks and ensure a proper metal-to-metal seal with the knife-edge construction.

Does this include the replacement O-ring?
The 168078 typically includes the necessary seals for the cartridge; however, we recommend having a Sporlan 791001 replacement O-ring kit on hand for comprehensive valve maintenance.
