Sporlan Controls 168147 Valve
The Sporlan Controls 168147 Valve, model SQE-5(2T)-SZP, is a purpose-built thermostatic expansion valve (TXV) engineered for low-temperature refrigeration applications. Designed to maintain precise superheat control, this valve is optimized for R-404A and R-507 refrigerants, providing a 2-ton nominal capacity. The externally equalized design ensures accurate refrigerant metering across the evaporator, even in systems with significant pressure drops. With 3/8" x 1/2" ODF sweat connections and a 60-inch capillary tube, this valve offers the versatility required for tight mechanical footprints. For field serviceability, it includes a 100 mesh removable strainer to protect the internal orifice from debris. Built to withstand a maximum operating pressure of 450 psi, this Sporlan 168147 valve utilizes a ZP thermostatic charge, specifically formulated to prevent motor overload during pull-down on low-temp systems including walk-in freezers and reach-in units.
Technical Benefits for Contractors:- MOP Functionality: The ZP thermostatic charge provides a pressure-limiting feature to protect the compressor motor during high-load start-up periods.
- Field Serviceability: Features a 100 mesh removable strainer, allowing for routine maintenance and cleaning without replacing the entire valve body.
- Precise Metering: Externally equalized ports compensate for pressure drops in the evaporator, ensuring the system operates at peak efficiency.
- Durable Construction: Heavy-duty brass body and stainless steel internal components designed for low-temperature refrigeration environments.
- Installation Flexibility: The 5-foot capillary tube allows for remote bulb placement to get the most accurate suction line temperature reading.
What is the benefit of the ZP charge on this Sporlan TXV?
The ZP charge is designed for low-temperature applications to provide a "Maximum Operating Pressure" (MOP) feature. This helps prevent the compressor from overloading by limiting the evaporator pressure during a hot pull-down.
Can this valve be used with R-507?
Yes, the Sporlan 168147 is fully compatible with both R-404A and R-507. Ensure your superheat adjustments are verified during commissioning as these refrigerants have slightly different pressure-temperature relationships.
Is the strainer replaceable on the SQE series?
This valve includes a 100 mesh removable strainer. It is recommended to inspect the strainer during any system repair to ensure proper flow and prevent orifice plugging in low-temperature cycles.
