Trane VAL7347 3/8" x 1/2" 3-Ton R410A Thermostatic Expansion Valve

The Trane VAL7347 is a thermostatic expansion valve (TXV) designed for residential and light commercial air conditioning systems using R410A refrigerant. This precision metering device regulates refrigerant flow to the evaporator coil, ensuring optimal system performance and efficiency across varying load conditions.

Key Specifications:

• Capacity: 3-Ton nominal cooling capacity
• Refrigerant: R410A (compatible with R410S systems)
• Connection Sizes: 3/8" inlet x 1/2" outlet (ODF)
• Valve Type: Thermostatic expansion valve with replaceable power element
• Construction: Brass body with corrosion-resistant components

This TXV features a thermostatic power element that senses suction line temperature and pressure to maintain proper superheat control. The valve automatically adjusts refrigerant flow to match system demand, improving energy efficiency and preventing liquid refrigerant from returning to the compressor. Designed for reliable performance in Trane and compatible HVAC equipment, the VAL7347 helps maintain consistent comfort while protecting system components from damage due to improper refrigerant metering.
