CGIS leads severe service valve task force to establish new standards

Mar. 12, 2017 - Last fall, an interest group led by CGIS president Ross Waters presented their request for a new standard practice — on defining reliable principles and parameters for what separates a severe service valve (SSV) from a general purpose valve) — to the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS).

A MSS technical committee determined the proposal would be a beneficial project to pursue and as a result, an official task force was created, to be led by Waters.

The task force will now determine the minimum requirements a valve needs to be able to perform to when faced with extreme conditions, whether from pressure, temperature, toxicity, solids or usage.

“By creating a rigorous standard for severe service valves to adhere to, we can ensure end-users can protect both their workers and the environment,” said Waters. “We’ve seen countless examples where general purpose valves were used in a severe service situation, which led to high operating costs, loss of process containment and control, and significant damage to the environment. This task force was created with the goal to drastically lower these statistics.”


Along with providing objective principles and parameters on how to define and identify SSVs, the proposed standard practice will also provide the basis of a definition that is currently being referred to in other MSS work, like Special Leak Test Methods and Procedures for Valves.

Over the upcoming year, the task force aims to determine a “clear and measurable definition and identification process” with the end goal of having a standard practice for end-users and manufacturers to follow, adding that this resource will be “critical” for selecting the right valve for the application going forward.

With more than 35 years of experience and offices through Canada and Australia, CGIS is the global supplier of valves, controls, and automation.
