Gas and Combustion effects (спецэффекты с возгоранием)

[lab]

Коллеги, здравствуйте,

Пожалуйста, помогите качественно перевести словосочетания:
gas control and valve management technology
Gas and Combustion effects

Контекст см. ниже, речь идет о спецэффекте на Олимпийских играх, когда на поверхости воды появляются огненные кольца.

Заранее благодарю за все идеи!

XXX and its suppliers were responsible for the development and commissioning of gas control and valve management technology that led to the creation of an iconic image – The Olympic Rings of Fire emerging from the ‘sea’. This concept, which allowed for the reveal of the rings to occur as 'Fire from Water' was made more challenging by the creative team’s desire to reveal the rings in separate stages, thereby delaying the full image and building dramatic tension. XXX worked with a world leading partner in the delivery of Gas and Combustion effects to manufacture and commission an extensive gas control system and valve train unit.

Не могу соединить в одно, но в качестве идей: "система управления потоком газа", "система управления клапанами подачи газа".
