Allied Air 1.851362 Txv R410A 3.5-5 Ton Ac

Product Description

The ALLIED AIR 1.851362 is a thermostatic expansion valve (TXV) designed for R-410A refrigerant systems in cooling-only applications. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level across a wide range of operating conditions. This valve is sized for 3.5- to 5-ton AC-only systems. Licensed HVAC technicians install and service this component as part of split-system or package air conditioning equipment.

This TXV is intended for residential or light commercial air conditioning systems operating on R-410A refrigerant in the 3.5- to 5-ton capacity range. It is suited for AC-only configurations where no heat pump reversing cycle is required. Technicians replacing a failed or improperly sized metering device with a direct OEM-style TXV will find this valve appropriate for that service scenario.

Key Features

• Rated for R-410A refrigerant — no cross-refrigerant substitution required
• Capacity range covers 3.5 to 5 tons for AC-only operation
• Designed as a direct OEM-style replacement TXV
• Modulates refrigerant flow to maintain correct evaporator superheat

Compatibility

Designed as an OEM-style replacement TXV for R-410A cooling-only split-system or package air conditioning equipment in the 3.5- to 5-ton capacity range.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before removing the existing metering device. Ensure the system is fully evacuated and leak-tested before recharging with R-410A. Follow equipment manufacturer wiring and piping diagrams and applicable local mechanical codes when completing the installation.
