The term Severe Service Valve (SSV) is commonplace to the industrial valve industry. The problem is no one really knows exactly what it means.

Most of us know when an application is severe. But what is it that makes it severe for a valve? Defining Severe Service Valves (SSVs) objectively is an important tool in attaining improved process control, safety, profitability, and environmental stewardship. SSVs can be defined as industrial valves specifically designed to perform in the most extreme conditions without failing. These conditions

There is no clear or universal industry definition or mechanism to describe and accurately define severe service valves (SSVs) and separate them from general purpose valves. Yet, such a definition would allow the industry to benefit from improved process performance, increased profitability, safety, and environmental protection. Most experts agree that SSVs are identified by applications, and that these applications are

Severe Service Valves (SSVs) mean different things to different people. Until today, defining SSVs had little if any global agreement or recognition. That is about to change as the Manufacturers Standardization Society (MSS) has accepted an application to produce a Standard Practice of defining them. This article provides information about the selection of SSVs in all industries but focusses on
