Check Valves Brochure

Weir SPM check valves are made of high strength steel and are precision manufactured to exact tolerances for clapper styles in 2" through 4" sizes, dart styles in 1" through 3" sizes, and CO2/nitrogen styles in 2" and 3" sizes. The clapper design features either a standard coating or superior abrasion and acid resistant coating to give longer operating life in corrosive applications.
