Product Details

Description

This high-performance Thermostatic Expansion Valve (TXV) is engineered for precise refrigerant metering in air conditioning and heat pump systems. Designed specifically for use with R-410A refrigerant, this valve accurately regulates the flow of liquid refrigerant into the evaporator coil, ensuring the system maintains optimal superheat and peak cooling efficiency. Replacing a faulty expansion valve is essential for preventing compressor damage, reducing energy consumption, and restoring consistent temperature control to your HVAC system. Built to withstand high-pressure environments, this durable component is a vital part of the refrigeration cycle for both residential and commercial cooling equipment.
