Severe Service Check Valves (SSCKVs) by DSS Valves

As the highest performance check valve on the market today, the DSS Severe Service Check Valve (SSCKV) is engineered to perform where conventional check valves fail. This valve handles high pressures, temperatures, corrosivity, and toxic media with ease.
Eliminating fugitive emissions was a major focus for the engineering team. We incorporated a retainerless body to remove potential leakage paths that exists in other check valve designs.
Our disc swings mostly out of the flow path producing a large bore with minimal obstructions; this results in very low pressure drop. Additionally, we have engineered the geometry of the bore using CFD software to improve flow characteristics.
Conventional Check Valves use discs that are comprised of as many as 7 different components, and they’re usually built to sloppy tolerances. DSS replaces all these components with one integral piece that cannot come loose and travel downstream. This removes the chance of failed components damaging pumps and other equipment down the line.
The leading cause of Check Valve failures is due to oversized bores which creates slamming issues. We have optimized the weight and size of our disc and the geometry of our inlet to overcome many of these concerns.
Utilizing our nimble supply chain and multiple manufacturing partners within driving distance of our factory, we can provide large bore valves, high alloys, and high-pressure class valves in a fraction of the time it takes our competitors.
The DSS SSCKV is the premium Check Valve solution for Severe Service applications that require zero leakage performance.
