The Sporlan 168080 is a high-precision QC-5 Black Q Cartridge designed for field-serviceable thermostatic expansion valves in small refrigeration and air conditioning systems. Engineered for the veteran contractor, this size #5 orifice assembly provides a specific flow profile compatible with R-22 systems at a 3-ton capacity, and R-404A, R-134a, or R-502 setups at a 2-ton capacity. The color-coded black top and included ID tag ensure immediate identification during rapid rack maintenance or rooftop repairs. This cartridge belongs to the Type Q series, offering an interchangeable orifice design that allows technicians to modify TEV capacity without removing the valve body from the liquid line. Built with a durable brass body and stainless steel internals, the QC-5 maintains precise superheat control across varying evaporator loads. It is a drop-in replacement part that requires a 4mm hex wrench for installation, ensuring a leakproof metal-to-metal seal when paired with standard Sporlan valve bodies. Key Benefits Modular Serviceability: Allows for quick orifice replacement to match system load changes without de-brazing the main valve body. Multi-Refrigerant Compatibility: Rated for 3 tons with R-22 and 2 tons with R-404A, R-448A, R-449A, and R-134a. Simplified Identification: Features a black color-coded top and a bendable ID tag for the capillary tube to prevent sizing errors in the field. Reliable Calibration: Maintains stable superheat levels in commercial refrigeration, walk-in coolers, and residential AC applications. Common Questions Which valve bodies are compatible with the QC-5 cartridge? This cartridge is specifically for use with Sporlan Type Q (conventional port) and Type BQ (balanced port) series valves. It is not designed for R-410A applications. What tool is required for installation? A standard 4mm Allen wrench is required to secure the cartridge into the valve body. Ensure the seating area is clean to maintain a leakproof joint. Does this kit include the O-ring? The 168080 kit typically includes the cartridge and the ID tag. If a replacement O-ring is needed, part number 791001 is the standard requirement for these assemblies. This item is not eligible for free shipping.
