York S1-VLV-012B-410 TXV
The York S1-VLV-012B-410 TXV is a precision-engineered OEM thermostatic expansion valve designed specifically for 1-ton residential and light commercial R410A systems. This metering device is critical for maintaining the correct evaporator superheat, preventing liquid slugging to the compressor while ensuring maximum heat transfer efficiency across the coil. Featuring 3/8 x 1/2 inch ODF sweat connections, this valve provides a reliable, leak-resistant bond for high-pressure 410A refrigerant lines. As a genuine York replacement part, it ensures direct compatibility with specific York, Luxaire, Coleman, and Guardian evaporator coils, eliminating the guesswork associated with universal aftermarket valves. Its balanced port design allows for stable operation across various ambient temperatures and load conditions, making it an essential component for restoring HVAC system performance and extending the service life of the compressor. When charging the system, this 1-ton TXV facilitates accurate refrigerant flow control to achieve the target subcooling and superheat required by manufacturer specifications.
Key Benefits- Ensures precise refrigerant flow control to maintain optimal system efficiency and cooling capacity.
- Designed for R410A compatibility, handling the higher operating pressures of modern air conditioning systems.
- Features durable ODF connections (3/8" inlet, 1/2" outlet) for a secure, brazed installation in the field.
- Protects the compressor by preventing liquid floodback through accurate superheat regulation.
- Authentic York S1-VLV-012B-410 replacement ensures exact factory specifications are met without performance loss.
Is this TXV compatible with R22 systems?
No, this valve is specifically calibrated for the pressure-temperature relationship of R410A refrigerant. Using it in an R22 system will lead to improper metering and potential compressor damage.
How do I tell if my York TXV has failed or is just hunting?
Check your suction pressure and evaporator superheat. If the superheat is consistently high regardless of load, or if the valve does not respond to a bulb temperature change, the power element or internal orifice may be compromised. Always verify that the sensing bulb is properly insulated and secured before diagnosing a failure.
Does this valve require an external equalizer line?
Yes, this model typically utilizes an external equalizer to account for the pressure drop across the evaporator coil, ensuring the valve maintains a constant superheat based on the actual coil outlet pressure.
