CGIS President Ross Waters received a special thanks from the Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry last week for his work on SP 151-2016. The first edition of the ‘Standard Practice for Pressure Testing of Knife Gate Valves’ was approved, and is expected to be published in fall of 2016.
Ross drew from his unique understanding of Knife Gate Valves, gained from over 36 years of experience, to help with the initial preparation of the first draft. The goal of this SP is to determine a uniform means of testing Knife Gate Valves commonly used in the “full open” and “full closed” types of service for isolation. This SP is not intended for use with control valves.
Establishing requirements and acceptance criteria for shell and seat closure pressure testing of high performance resilient, non-metallic (e.g. ceramic), and metal-to-metal seated Knife Gate Valves of all types was key to this SP. This is important to the industry because prior “general purpose” Knife Gate Valve performance, as specified in MSS SP-81, did not provide the isolation quality that many applications demanded. MSS SP-151-2016 provides users with a high-performance standard equal to the security and risk reduction that severe service applications require.
Check out the latest case study put together by one of our Severe Service Valve (SSV) experts, Derek Feltham. Learn how he helped PotashCorp solve a complex problem with the use of a unique Severe Service Control Valve from Flowserve – the Multi-Z. Click here for the full story.
The term Severe Service Valve (SSV) is commonplace to the industrial valve industry. The problem is, no one really knows exactly what it means.
CGIS is in the process of establishing the exact definition. Once in place and approved by the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS for short), there will be a benchmark and rating system to identify what constitutes a Severe Service Valve (SSV), and how it differs from a General Purpose Valve (GPV).
In the meantime, we pulled from our internal best practices and over 35 years of experience to put together this brief guide. We hope you’ll consider these 6 key factors for selecting the right valve for your application. Download the guide here.
The severe nature of the world of hydrometallurgy demands specialized designs that can withstand the corrosiveness and solid build-ups that occur. Check out our in-depth comparison of Push-Through Knife Gates vs Guided Shear Gates, featured in the May 2016 Issue of Valve World Americas.Read More

CGIS signs agreement to participate in the Materials and Reliability in Oil Sands (MARIOS) program run by Alberta Innovates – Technology Futures or AITF (formerly the Alberta Research Council). The Oil Sands is a key player in Canada’s mining industry and CGIS believes that investing in research and development will provide long-term benefits that will not only help the industry itself but will create a safer environment for workers.
Specifically, CGIS is contributing to this body of work by testing valves in the slurry loop. The goal of this test is to retrieve data on life expectancy of valves in systems operating with abrasive and/or erosive slurries. This test will benefit end-users in the mining industry as it uses machinery from a neutral third party to confirm the estimated life cycles of the tested valves. It is extremely rare to be able to test valves through a slurry loop so this opportunity is significant for both CGIS and the Oil Sands. By specifying the number of valves cycles, we can better estimate the valve’s life expectancy when installed in other types of slurries.Read More
Sep 2015 – “The Case for a Severe Service Standard” is now published on Valve Magazine‘s website. With major changes in the industry and an increased expectation for worker safety, the need for a Severe Service Valve category is critical. We can and should expect more from industrial valves today. Read how you can get involved with creating a Severe Service Valve category. Click here to read the article.Read More
