Inline Check Valves


Armstrong’s inline check valves are ideally suited for refrigerant flow control applications. The valves open wide for flow. These valves close quickly and are reliable when flow reversal occurs. The inline check valves feature a plated body, stainless steel disc and spring to enable them to withstand expected industrial refrigeration conditions.
