York S1-4190 Expansion Valve 320735-701 Robust Connectivity: Integrated 1/4 inchFor service technicians maintaining older R22 infrastructure, the York S1 4190 Expansion Valve provides critical metering precision for 2 to 3. 5 ton HVAC systems. This thermostatic expansion valve (TXV) is engineered specifically for R22 refrigerant, ensuring high efficiency heat transfer by maintaining consistent superheat across the evaporator coil. As a non bleed expansion valve, the S1 4190 prevents refrigerant bypass during the off cycle, which
