Description
The Copeland TFES-Series Thermal Expansion Valve (TXV) — model TFES 20 ZAA 5FT 5/8X7/8 ODF S/T — is a precision-engineered refrigerant metering device designed for high-capacity R410A HVAC systems. Built with a straight body configuration and a 5-foot capillary tube, this valve delivers reliable, responsive refrigerant flow control in demanding commercial applications up to 20 tons of capacity.
The externally equalized design ensures accurate superheat control even in systems with significant pressure drop across the evaporator, making it ideal for larger coils and multi-circuit evaporators. The wide range charge provides a broad operating envelope, accommodating variable load conditions without sacrificing efficiency or stability.
