Description
The Copeland 064993 (Model ACK-26) is a heavy-duty sweat check valve engineered for dependable one-directional refrigerant flow control in commercial and residential HVAC and refrigeration systems. Designed to prevent backflow and protect system components, this valve integrates a built-in 30 mesh stainless steel strainer that captures debris and contaminants before they can damage compressors, expansion devices, or other downstream components — eliminating the need for a separate inline strainer.
