The industrial series ball check valves are designed for reliable performance and easy maintenance. The double union body allows quick disassembly for service, while the venturi-style oversized body in the 4" valve ensures maximum flow with a standard 3" FNPT connection. Although the valve has 3" end connections, the internal passage is expanded to the equivalent of a 4" bore, reducing pressure loss and boosting flow capacity. These valves are fully rebuildable, resistant to many chemicals, and include a foot valve screen end connector for versatile use in industrial and fluid-handling systems.
