The Sporlan 168183 BQE 3X4 SAE Body is a professional-grade, brass bar body component designed for thermostatic expansion valve (TXV) assemblies in high-performance refrigeration and air conditioning systems. Engineered as a 3/8" x 1/2" SAE flare configuration with a 1/4" external equalizer, this Sporlan BQE valve body utilizes a balanced port design. This critical feature ensures precise pin and port alignment, preventing changes in pressure drop across the valve from influencing system operation—essential for equipment facing widely varying ambient conditions. This OEM Sporlan 168183 body is part of a three-component system, allowing technicians to match specific cartridges and thermostatic elements to the application's required tonnage and refrigerant type. It features a 100-mesh removable strainer to protect the internal orifice from debris, ensuring long-term reliability in commercial refrigeration, food storage, and HVACR systems. With a maximum operating pressure of 450 PSI (standard) or up to 700 PSI for R-410A applications, this externally equalized body is the industry standard for maintaining stable superheat across a broad capacity range from 1/8 to 5 tons. Key Benefits: Balanced Port Design: Maintains accurate refrigerant flow control even during significant head pressure fluctuations. Removable 100-Mesh Strainer: Simplifies maintenance by capturing system contaminants before they reach the valve seat. Three-Component Versatility: Allows for field-replaceable cartridges and elements to customize valve performance for R-22, R-134a, or R-404A systems. SAE Flare Connections: Provides secure, leak-proof 3/8" inlet and 1/2" outlet mechanical joints without the need for brazing. Common Questions: Is the cartridge included with the 168183 body? No, this is the valve body only. To complete the assembly, you must select the appropriate BQC cartridge and thermostatic element based on your system's refrigerant and capacity requirements. Can this body be used in heat pump applications? Yes, the Sporlan BQE series is well-suited for heat pump duty and air conditioning systems where external equalization is necessary for optimal evaporator efficiency. Does this valve body support bi-directional flow? While the balanced port construction handles varying pressures effectively, verify the specific cartridge and system configuration for bi-directional application requirements.
