Carrier P530-4152 Txv R-410A 1.5 to 2 Ton Expansion Valve

Product Description

The CARRIER P530-4152 is a universal thermal expansion valve (TXV) designed for R-410A refrigerant systems rated from 1.5 to 2 tons. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level across varying load conditions. This keeps the system operating efficiently and protects the compressor from liquid slugging. It is installed by licensed HVAC technicians as part of a split-system or package unit refrigerant circuit. The P530-4152 universal design makes it suitable for retrofit and replacement work where an OEM valve has failed or needs to be upgraded to handle R-410A service.

This valve is intended for residential and light-commercial cooling applications using R-410A refrigerant at 1.5 to 2 ton capacities. It fits into the liquid line at the inlet of the evaporator coil and works with the system distributor and sensing bulb assembly to regulate refrigerant flow dynamically. Technicians working on split-system air conditioners and heat pumps in the 1.5 to 2 ton range will find this valve applicable to retrofit scenarios where a universal replacement is acceptable.

Key Features

• Rated for R-410A refrigerant systems in the 1.5 to 2 ton capacity range
• Universal design supports retrofit and OEM replacement applications
• Regulates refrigerant flow to maintain proper superheat at the evaporator outlet
• Protects compressor from liquid refrigerant slugging under varying load conditions
• Compact form factor at 2.8 inches overall dimension for tight installation spaces

Compatibility

Designed as a universal OEM-style replacement TXV for R-410A residential and light-commercial cooling systems in the 1.5 to 2 ton range.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all system refrigerant and relieve system pressure before removing the existing TXV. Properly braze or connect the new valve per the manufacturer orientation markings, and ensure the sensing bulb is mounted securely to the suction line with proper insulation. After installation, evacuate the system to the required micron level before recharging with R-410A to the manufacturer-specified charge.
