Crane Aloyco® Stainless Steel Check Valves


Aloyco® stainless steel check valves are corrosion-resistant valves that prevent reverse flow in piping systems. They come in Y-pattern and T-pattern designs and are constructed of stainless steel alloys like CF8M (type 316) stainless steel and Alloy 20 that withstand harsh chemicals and extreme temperatures (-20 to 850°F). Aloyco check valves have flanged, socket weld, and threaded end connections and range from 1⁄2” to 24” in size, with pressure ratings from 150 to 600 psi.

These rugged check valves provide reliable protection for pumps, compressors, and other equipment in corrosive environments like chemical processing, mining, and wastewater treatment facilities.
