Lennox Check Valves

Lennox Check Valves allow fluid or refrigerant to flow in only one direction, preventing backflow that can damage pumps, compressors, and coils. Available in spring-loaded and swing-type configurations, these valves feature low pressure drop and durable seals. Installing Lennox Check Valves protects system components, maintains proper flow direction, and ensures reliable operation in hydronic, condensate, and refrigeration circuits.
