Clarke Valve, developer and manufacturer of the world’s most compact and efficient control valve, announced today that it has achieved the initial certification of the Dilating Disk™ Valve under ISO 15848-1:2015.
ISO 15848-1:2015, “Industrial valves – Measurement, test and qualification procedures for fugitive emissions” is the latest in a growing list of performance benchmarks and certifications to be earned by the innovative Dilating Disk™ Valve. ISO 15848-1 addresses both isolation valves and control valves, and specifies the testing procedures for the evaluation of the external leakage of volatile air pollutants, from the valve stem shaft seals and valve body joints.
Under this specific standard, a control valve must be cycled from 40% open to 60% open, with a minimum of 20,000 cycles for the first rating (CC1). To date, the Dilating Disk™ Valve has achieved the CC1 standard, with a proven tightness of Class AM, emitting less than 50 parts per million by volume (ppmv) of methane. This tightness class is the most stringent fugitive emissions measurement in the world, and serves as yet another major validation of the Dilating Disk™ Valve design.
“Clarke Valve sits at the intersection of reducing the cost of flow control and the fight to eliminate fugitive emissions,” said Kyle Daniels, President and CEO. “We are proud to be an OGCI Climate Investments portfolio company, and we are working non-stop with OGCI partners to implement this emissions-reduction technology in the field as quickly as possible. Studies estimate that a single valve using legacy designs and technology could emit as much as 10 tons of carbon dioxide equivalent each year. Testing has shown that the Dilating Disk™ Valve reduces this figure by at least 95%, and we are focused on driving the adoption of this technology across the spectrum of industries that have the potential to emit harmful pollutants into the atmosphere.”
Yarmouth Research and Technology, LLC, the world leader in valve testing services since 1992, is Clarke Valve’s chosen testing partner for ISO 15848-1 and other critical standards. Yarmouth Research previously conducted the API 641 certification of the Dilating Disk™ Valve, and will oversee continued testing of the Dilating Disk™ Valve under ISO 15848-1, until the CC2 (60,000 cycles) and CC3 (100,000 cycles) thresholds are met.
