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

Why Use Severe Service Valves?
Outdated valve specifications are a common sight in the industry.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, piping systems 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.
Defining Severe Service Valves
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.

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, how it differs from a General Purpose Valve, and the objective criteria required to identify severe service applications.
