Sporlan Check Valves are critical components in refrigeration and HVAC systems, designed to permit unidirectional flow and prevent reverse flow, thereby maintaining system integrity and efficiency. These valves are available in various models, such as the CK3 series, and connection sizes, including 3/4" ODF, to accommodate different system requirements. By ensuring proper flow direction, they protect compressors and other sensitive components from potential damage caused by backflow.
