The DFT® Model SCV-R® Check Valve is a non-slam spring-assisted check valve designed for applications requiring higher cracking pressures than the DFT® Model SCV® check valve. The SCV-R® is a self-contained check valve that installs directly in a pipeline and contains all of the proven features of the SCV® check valve.

The standard SCV-R® valve features a 316 stainless steel (A351 CF8M) body and seat with a 316 stainless steel disc and Inconel® X-750 spring, as well as a Zelon® o-ring body seal with socket weld or threaded female NPT end connections.
