Description
The Daikin-McQuay 300047538 4-Ton Thermal Expansion Valve (TXV) is a metering component that operates as an essential part of HVAC systems, regulating refrigerant flow into the evaporator coil. It is used in air conditioning and refrigeration units to control cooling output across commercial applications. Its capacity, 60-inch capillary tube, and 5/8 x 5/8 ODF connections support precise installation. Its sensing mechanism adjusts refrigerant feed based on load conditions, supporting stable temperature control and reducing the risk of inefficiency or damage.
