Description
The Copeland 056225 (Model HFES 1 RZ 5FT 3/8 x 1/2 ODF S/T) is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in low-temperature refrigeration applications. Featuring an externally equalized design, this valve accurately compensates for pressure drop across the evaporator, ensuring consistent superheat control and optimal system efficiency even in demanding low-temperature environments.
With a rated capacity of 1 ton on R502 refrigerant and a low-temperature charge, this TXV is well-suited for commercial refrigeration systems, walk-in coolers, freezers, and other low-temperature evaporator applications. The straight-body configuration and 3/8″ x 1/2″ ODF sweat connections simplify installation and provide leak-free, brazed joints for long-term reliability.
The 5-foot capillary tube provides ample length for flexible bulb placement on the suction line, allowing technicians to achieve accurate sensing and proper superheat adjustment during commissioning.

Why Choose the Copeland 056225 TXV?
The externally equalized design makes this valve the preferred choice for evaporators with multiple circuits or notable pressure drops, where an internally equalized valve would result in poor superheat control and reduced system efficiency. The low-temperature charge ensures the valve responds accurately across the full operating range of low-temp applications, preventing liquid flood-back and protecting the compressor. Sweat connections provide a permanent, vibration-resistant joint that holds up in demanding refrigeration environments.
