These inline valves allow free flow in only one direction, prevent backflow, and meet the industry's need for higher operating pressures. They also are used for relief and by-pass functions; however, they should not be used as safety relief valves. Kepner's Flexible Seal Seat™ combines metal-to-metal contact with a resilient seal seat ensuring bubble-tight shutoff of liquid or gas. This is an ideal choice for applications that require positive leak-tight sealing and long service life at pressures to 6000 PSI. Standard and specialty valves handle a wide variety of applications.

Features and Benefits:

• Flexible Seal Seat™ for zero leak (bubble-tight) sealing to 6000 PSI
