Clarke Valve shatters benchmarks for reliability and fugitive emissions

Clarke Valve, an OGCI Climate Investments portfolio company, announced today that its proprietary Shutter Valve has successfully completed the maximum certification level of 100,000 mechanical cycles and achieved the minimum allowable fugitive emissions, during independent testing for ISO 15848-1:2015 certification.
Under ISO 15848-1, control valves must cycle from 40% open to 60% open, while meeting one of the tightness class ratings for methane leakage: tightness class CM signifies allowable leakage of ≤ 500 parts per million by volume (ppmv); BM is for ≤ 100 ppmv; and AM is the world’s most stringent standard for methane leakage, at ≤ 50 ppmv.
One of the other key ratings addressed by ISO 15848-1 is reliability, as measured by the endurance class that a control valve can surpass, while maintaining a CM tightness class or better: endurance class CC1 signifies 20,000 mechanical cycles completed; CC2 is for 60,000 mechanical cycles; and CC3 is the highest endurance threshold under ISO 15848-1, at 100,000 cycles.
“The Shutter Valve has shattered the previously held standards for low emissions by a control valve, as expected,” said Kyle Daniels, President and CEO of Clarke Valve. “It achieved the ISO 15848-1 CC3 endurance rating for 100,000 mechanical cycles, while allowing a maximum of 2 ppmv, during more than 3 weeks of continuous testing. We have clearly demonstrated that we have the best fugitive emissions solution on the market, and we look forward to deploying this technology through the OGCI member companies.”
Owing to its unique design, the Shutter Valve is one of the few control valves to qualify for both ISO 15848-1 and API 641 certification, as confirmed through independent testing by Yarmouth Research and Technology, LLC. API 641 is the American Petroleum Institute’s fugitive emissions standard for quarter-turn valves, which is the category of valve the Shutter Valve belongs to, and is the most common category of valve in use today.
