The term Severe Service Valve (SSV) is commonplace to the industrial valve industry. The problem is, no one really knows exactly what it means.
Acting as the SSV task force leader for the Manufacturers Standardization Society (MSS), CGIS is at the forefront of establishing the benchmark and rating system to identify what constitutes a Severe Service Valve, and how it differs from a General Purpose Valve.
Severe Service Valves can be broken down into three main categories. To maintain consistency across the industry, we recommend using the following abbreviations.
Outdated valve specifications are a common sight in the industry. It is extremely concerning as there have been technical advances in valve design, yet no alterations to the valve specifications themselves. The operating conditions of pressure, temperature, process volume and energy costs are drastically different than they were only 30 years ago. Maintenance staff are fewer, are operating under higher pressures and temperatures, and the push to produce more revenue from fewer resources is greater than ever before.
SSVs play an important role as new processes with aging technology creates immediate dangers to workers and their surrounding environment. Safety is a priority in our industry and we believe that everyone has the right to go home safely at the end of each day. Severe Service creates dangerous environments and when not handled correctly, can endanger the lives of many and cause long term damage to its surrounding environment. Valves are a significant safety feature and should be held to a higher regard, especially in a severe service application. By designating certain applications as Severe Service and then using appropriate valve suppliers to source valves, we can reduce the risk of critical leaks.
A Severe Service category has yet to be objectively defined but we understand that this definition is critical to the industry. CGIS Chairman, Ross Waters, has been at the forefront of this cause and has presented his paper, “Defining Severe Service Valves”, internationally. At CGIS we know that you can and should expect more from today. We believe that using suppliers who specialize in SSVs, applying a series of steps in qualifying them and separating general purpose applications from the more severe applications, can save workers’ lives and protect our environment.

In June of 2015, the first documented work towards defining SSVs began with an Article published in Valve Word Americas. Since then, a growing and widening interest has arisen to help push this initiative towards completion. One needs only search for the phrase “Severe Service Valves” to obtain a plethora of ideas, articles, opinions and guidance.

The technology behind industrial applications such as Hydrometallurgy continues to evolve, as do the corresponding regulations and specifications that ensure the safety of workers and the environment. More often than not, the valves being used in Hydrometallurgy applications are known as Severe Service Valves (SSVs) due to their ability to withstand the extreme conditions.
