Apollo 62-100 Series ball cone spring check valves ensure that fluids flow in one direction while blocking reverse flow, thereby preventing contamination, system damage and inefficiencies. By allowing the flow of fluids only in the desired direction, these valves maintain the integrity of pipelines, pumps and equipment, enhancing system reliability and safety. They feature stainless steel construction for durability and resisting corrosion on exposed surfaces. These check valves come with threaded FNPT x FNPT connections to simplify installation by securely attaching to pipes or fittings for reliable fluid control. They are equipped with PTFE (Reinforced Teflon) ball checks for corrosion resistance and chemical compatibility. These valves are equipped with stainless steel springs, providing resilience and maintaining long-term valve functionality. They are available in sizes of 1/4, 3/8, 1/2, 3/4, 1, 1.25, 1.5 and 2 inches.
