Block Type R134a Expansion Valve OEM 80211-SDA-A01 Honda Civic Accord CR-V Element 1.5Ton TXV Direct Replacement

The Silk TXV-80211-DB is a precision-engineered block type thermal expansion valve designed as a direct-fit replacement for Honda and Acura vehicle air conditioning systems. Manufactured to exact OEM specifications with a forged brass body and stainless steel diaphragm assembly, this expansion valve delivers accurate refrigerant metering and stable evaporator superheat control across the full spectrum of operating conditions. The four-port pad-mount flange configuration with standard #6, #8, #10, and #12 port sizing matches the original mounting geometry exactly, eliminating the need for adapter fittings, reducer bushings, or field modifications during installation. Every unit undergoes individual flow-rate calibration on automated test benches in our ISO 9001:2015 and IATF 16949 certified production facility, with serialized test records maintained for full batch traceability. For automotive parts distributors, independent repair shops, and Honda specialist service centers seeking reliable aftermarket AC components, this TXV offers an optimal combination of OEM-grade manufacturing precision and competitive aftermarket value.

• Direct-Fit Honda Compatibility: Engineered as a drop-in replacement for Honda and Acura vehicles utilizing OEM part numbers 80211-SDA-A01, 80211-S5A-003, and 80211-S5A-J01, with exact pad-mount bolt pattern alignment and pre-calibrated superheat settings that require no field adjustment during installation.
• Forged Brass Body Construction: The valve body is precision-machined from high-density forged brass stock (CuZn39Pb3), providing superior resistance to corrosion, vibration fatigue, and thermal expansion stress compared to cast aluminum alternatives commonly found in budget aftermarket TXVs.
• Stainless Steel Diaphragm Mechanism: The sensing diaphragm and pushrod assembly utilize food-grade 304 stainless steel, delivering consistent actuation force across a -40°C to +120°C temperature range without elastic degradation or hysteresis drift over thousands of thermal cycles.
• Precision-Calibrated R134a Orifice: The internal orifice plate is laser-drilled and flow-bench calibrated specifically for R134a refrigerant thermodynamic properties, achieving a nominal capacity of 1.5 tons with superheat control accuracy within ±1°C under standard SAE J2767 test conditions.
• Standardized Four-Port Interface: Features #6 liquid inlet, #8 suction inlet, #10 liquid outlet, and #12 suction outlet sizing on a common pad-mount flange, compatible with OEM hard-line and hose assemblies without requiring adapter fittings or reducer bushings.
• 100% Production-Line Testing: Every unit is individually tested for internal leakage, external leakage, opening superheat setpoint, and nominal capacity before packaging and shipment, with serialized test records maintained for full batch traceability and quality documentation.
• Broad Honda Platform Coverage: One SKU covers multiple high-volume Honda and Acura models including Civic (2001-2011), Accord (2003-2012), CR-V (2002-2011), Element (2003-2011), and Acura RSX (2002-2006), reducing inventory complexity while maximizing parts turnover.

The TXV-80211-DB block type expansion valve is engineered for direct-fit installation on a comprehensive range of Honda and Acura passenger vehicles equipped with R134a air conditioning systems. Primary vehicle applications include Honda Civic (EM2, ES1, EP3 chassis, model years 2001 through 2011 with 1.7L D17 and 2.0L K20 engine configurations), Honda Accord (CM4, CM5, CM6 chassis, 2003 through 2012 covering both 2.4L K24 and 3.0L J30 V6 engine variants), Honda CR-V (RD4, RD5, RD7, RE1 chassis, 2002 through 2011), and Honda Element (YH1, YH2 chassis, 2003 through 2011). The valve is also compatible with Acura RSX (DC5 chassis, 2002-2006) and certain Acura TSX (CL9 chassis, 2004-2008) models that share the same Honda K-series engine platform and Denso air conditioning system architecture. Cross-reference OEM part numbers include 80211-SDA-A01, 80211-S5A-003, 80211-S5A-J01, and 80211-S5D-J01. The valve is equally suitable for original equipment replacement in factory AC systems and for aftermarket repairs performed by professional automotive technicians. Its calibrated R134a metering characteristics also make it appropriate for retrofitted systems originally designed for R12 refrigerant, provided the system has been properly flushed, evacuated, and recharged with compatible PAG compressor oil. Always verify fitment against the vehicle VIN and existing OEM part number before ordering to ensure correct application.

Each TXV-80211-DB expansion valve is individually sealed in an anti-static poly bag with silica gel desiccant pack to prevent moisture ingress during transit and storage, then placed in a custom-fitted inner box with die-cut foam cushioning that isolates the valve body and port sealing surfaces from external impact forces. Inner boxes are packed into export-grade five-layer corrugated master cartons, with each carton holding 50 units and featuring reinforced corner posts for stacking strength during ocean freight and intermodal container transport. Every production batch is accompanied by a certificate of conformance documenting the test results for opening superheat, internal leakage rate, external leakage verification, and rated capacity at nominal operating conditions. We maintain full batch traceability with serial-numbered test records archived for a minimum of three years. Our quality management system is certified to ISO 9001:2015 and IATF 16949:2016 standards, and all expansion valve products comply with SAE J2767 and IMACA 300 testing protocols. We offer a standard 12-month warranty against manufacturing defects from the date of shipment, with extended warranty options available for volume contract customers. Neutral packaging and private-label branding services are available upon request for distributors seeking to market under their own brand identity and part numbering system.
