York S1-025-51449-000 TXV Valve 320819-301 ensure the sensing bulb isThe York S1 025 51449 000 is an OEM thermostatic expansion valve (TXV) and distributor assembly engineered for precise refrigerant metering in specialized HVAC systems. Featuring a unique 12 tube distributor configuration and a #6 orifice size, this component is critical for maintaining optimal superheat levels across the evaporator coil. By accurately balancing bulb pressure and evaporator pressure, the valve prevents liquid floodback to the
