Clarke Valve achieves fugitive emissions reduction ISO certification

Control valves manufacturer Clarke Valve has achieved initial certification of its Shutter Valve under ISO 15848-1:2015.

The ‘Industrial valves – Measurement, test and qualification procedures for fugitive emissions’ ISO standard covers isolation valves and control valves. It specifies the necessary testing procedures to evaluate external leakage of volatile air pollutants from the valve stem shaft seals and valve body joints, according to the company.

Under the ISO certification 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).

Clarke Valve’s Shutter Valve has achieved CC1, emitting less than 50 parts per million by volume of methane.

“Clarke Valve sits at the intersection of reducing the cost of flow control and the fight to eliminate fugitive emissions,” said president and CEO Kyle Daniels. “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 Shutter 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.”
