Clarke Valve technology approved for oil and gas operations in Canada

Valve manufacturer Clarke Valve, a portfolio company of Saudi Aramco Energy Ventures, Chevron Technology Ventures and OGCI Climate Investments, has been awarded a new patent to protect its control valve technology in Canada.

The Canadian Intellectual Property Office awarded the company Canadian Patent number 2,892,194 for its Shutter Valve, which protects the unique low-torque design of the technology. The Shutter Valve has been validated by the oil and gas industry as a highly reliable innovation in control valve and isolation valve technology.

"We are proud to have earned this patent and look forward to increasing our market presence in Canada," said Kyle Daniels, president and CEO of Clarke Valve. "This IP protection complements the countrywide Canadian Registration Number (CRN) secured earlier this year for the Shutter Valve that is now approved for sale and operation across Canada."

The design of the Shutter Valve provides equivalent flow rate and flow characteristics at a fraction of the size, cost and weight of other globe valves commonly used for process control applications. The valve uses three interlocking petals that are mounted to a ring gear by pivot arms, to deliver precision throttling in a compact, low-torque and cost-effective package.

The valve also reduces fugitive methane emissions by over 95% compared to low-emissions globe valves and is one of just a few control valves to earn API 641 and ISO 15848-1 certifications.
