Chemical Injection Throttle Valve (CTV)

Chemical injection throttle valves (CTVs) deliver continuous, controlled subsea injection of a wide variety of chemicals to improve flow performance and enhance oil recovery.


1,000+ CTVs Supplied Worldwide

We put our first CTV on the seabed in 1995. Today, we have supplied more that 1,000 CTVs worldwide.


Using CTVs in Harsh Subsea Environments

Our CTVs are suitable for use in harsh subsea environments with pressures up to 1,035 bar (15,000 psi) and depths of 3,630 m (11,900 ft).

The CTVs are remotely operated and ROV retrievable. They are available in high-flow, medium-flow, and low-flow configurations.



High-Flow CTV

Flow rates: 2–200 l/min (760–76,081 gal/day)
