Chemical Injection Throttle Valves

Delivering cost efficiency with self-cleaning, clog-resistant designs

Chemical injection throttle valves (CTVs) regulate the flow of chemicals—scale, wax, and corrosion inhibitors, for example—delivered to subsea production systems. Their functions are diverse, from flow control to metering and highly accurate dosing.

CTVs effectively eliminate the need for topside injection and dedicated umbilical lines. This enables the design and deployment of more efficient umbilicals, saving operators valuable expenditure and delivering benefits when considering umbilical transport, manufacturing, and installation.
