York 025-40900-006 TXV

The York 025-40900-006 TXV is a high-capacity thermostatic expansion valve designed for precision refrigerant metering in large-scale commercial HVAC systems. Rated for 37.1 tons, this R410A expansion valve features 1-1/8 inch ODF solder connections, ensuring a reliable, leak-free fit within the liquid line. As an OEM Johnson Controls York part, it is engineered to maintain the correct evaporator superheat across varying thermal loads, preventing liquid slugging and protecting the compressor. The balanced port construction compensates for high pressure drops, making it an essential component for maintaining system efficiency in chiller and large split-system applications. Field technicians should verify 025-40900-006 compatibility with existing sensing bulb locations to ensure optimal response times. This HVAC replacement TXV provides the mechanical durability required for high-duty cycle environments where precise refrigerant flow control is critical for meeting demanding cooling setpoints.

• High-Capacity Precision: Optimized for 37.1-ton cooling loads using R410A refrigerant.
• OEM Reliability: Genuine S1-025-40900-006 replacement ensures exact mechanical specifications and mounting alignment.
• Durable Construction: Built to withstand commercial pressure requirements and minimize flash gas issues.
• System Protection: Highly responsive thermostatic element prevents evaporator flood-back and optimizes heat transfer.

What are the connection sizes for the York 025-40900-006?
