HOUSTON – Oceaneering International’s Rotator business has launched a topside chemical throttle valve (T-CTV).
The new valve leverages existing field-proven technology to address operational requirements for efficient topside chemical dosing.
It is also said to be ideal for unmanned and remotely operated applications across industries and can be configured with optional Wi-Fi capabilities.
The valve, the company claims, is also the industry’s only design that combines a full-flush position with an integrated mechanical scraper. This feature ensures contamination tolerance and delivers long-term performance without the need for filters.
Tommy Tolfsen, T-CTV Product Manager at Rotator, said: “Historically, Rotator’s focus has been on subsea valves and we’re excited about this opportunity to expand into the topside market with an industry-leading solution. Our T-CTV delivers a fully automated chemical dosing package. It combines continuous and accurate flow measurement with automatic flow regulation in a modular, plug-and-play design.
“With the appetite for unmanned platforms growing, we wanted to make sure our T-CTV is ready for full, remote operation.”
The accuracy of the valve results in less chemical waste, according to the company. The valve boasts ± 0.2% of reading via continuous Coriolis flow measurement. The T-CTV control system uses continuous, live feedback from the Coriolis flow meter to automatically regulate and continuously display flow rates.
The valve’s helical flow path provides stable, controlled flow throughout the entire operating range. A fully programmable deadband is set to further optimize flow performance. The accuracy and reliability of the new valve will ultimately reduce opex via lowered chemical costs and improved uptime, the company said.
