York S1-025-53940-000 TXV Valve 0x0.375 Orifice R454B Sanhua

Description

The York S1-025-53940-000 is an OEM thermostatic expansion valve (TXV) engineered for precise refrigerant flow control in systems operating on R-454B, a next-generation low-GWP refrigerant blend. Manufactured by Sanhua — a globally recognized leader in HVAC and refrigeration components — this valve is a direct factory replacement designed to restore peak system efficiency and maintain proper superheat regulation in York equipment.

Product Overview

The TXV (thermostatic expansion valve) meters the flow of liquid refrigerant into the evaporator coil, maintaining optimal superheat and protecting the compressor from liquid slugging. With a 0x0.375 orifice specification, this valve is precisely sized for the refrigerant mass flow requirements of its target application. Designed for R-454B refrigerant, it is well-suited for modern, environmentally compliant HVAC systems transitioning away from higher-GWP refrigerants.

Key Features

• OEM York replacement TXV valve — ensures proper fit and performance
• Orifice size: 0x0.375 — factory-matched for correct refrigerant flow rate
• Compatible refrigerant: R-454B (low-GWP next-generation refrigerant)
• Manufactured by Sanhua — globally trusted HVAC refrigeration component supplier
• Maintains accurate superheat control to protect compressor and optimize efficiency
• Direct factory replacement for applicable York equipment

Application

• Designed for use in York HVAC systems utilizing R-454B refrigerant
• Suitable for residential and light commercial cooling applications
• Replaces worn or failed TXV components to restore system performance

Why Choose an OEM TXV?

Using a factory-specified TXV ensures the valve’s internal components — including the sensing bulb, power element, and orifice — are calibrated to the exact operating parameters of your York system. An improperly sized or mismatched TXV can result in poor efficiency, compressor damage, or comfort complaints. The S1-025-53940-000 eliminates guesswork and delivers a verified, manufacturer-approved solution.
