The new Series S250 in-line check valves from Bonomi (Charlotte, NC) 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. Benefits include:
- Electron beam welding at the end cap-to-body connection creating a unibody for leak-free service.
- The low-cracking .50-PSI spring-loaded FKM (Viton) seat, providing high flow capacity, minimal head loss and dependable, bubble-tight protection against reverse flow.
- Availability in six sizes, FNPT threaded from 1/2” to 2”. The new valves are rated to 250 WOG with an operating temperature range of -4˚F to 302˚F.
