The Series S250 in-line check valves feature a cold-formed 316 stainless steel body that gives users the highest Cv at the lowest cost. The metal forming process allows an improved flow profile inside the valve body to minimize head loss. It also eliminates machining for reduced manufacturing cost.
The product is electron beam welded at the end cap-to-body connection creating a leak-free service. The product features a .50-PSI spring-loaded FKM (Viton) seat.
Available in six sizes, FNPT threaded from ½- to 2-inches, the new valves are rated to 250 WOG with an operating temperature range of -4F to 302F.
