The Georg Fischer Type 369 Check Valve is an ideal solution for a variety of applications. Mounted between two ANSI flanges, the design of the 369 valve allows for easy installation or removal in the field. The valve is available in versions with or without springs. The spring loaded version works well in horizontal installations where many check valves may not. With the standard 316 stainless steel spring or the optional hastelloy C, the valve can be subjected to a wide range of chemical mixes. The 369 valve, with a size range of 1½ to 12 inches, is a perfect fit for many of today's industrial applications.
