For more than five decades, Emerson has worked alongside some of the world’s largest energy companies to provide innovative products for critical process applications. Our work includes the Vonk range of choke valves, which have built a reputation for high quality, technologically-advanced valve design in the oil and gas industry.

Vonk chokes are based on the innovative combi-choke control valve principle, delivering high performance and reduced operating costs, while also meeting our customers’ requirements for increasingly stringent safety, noise, and emission requirements.

Vonk chokes comply with the most stringent requirements of the European Directives and harmonized standards including Pressure Equipment Directive (97/23/EC PED) and ATEX 94/9/EC for potentially explosive atmospheres.
