Advanced Technology Valve (ATV) designs and produces subsea valves and actuators that operate in water depths up to 3,000 m (9,842 ft), and other products for hydrocarbon processing on platforms.

The company is based in Colico in northern Italy on the eastern shore of Lake Como. Over the past two years, ATV has increased its manufacturing capacity after acquiring 20,000 sq m (215,278 sq ft), of extra land of which 5,700 sq m (61,354 sq ft) is covered, and establishing a new welding shop that features 21 robotic welding machines.

In addition, the company has expanded its machining capability with several latest-generation CNC lathes and machining centers, and doubled its assembly and testing area. All production phases are performed in-house. It has also steadily recruited personnel, employing 400 staff now compared with 40 in 2007.

To test the valves for deep/ultra-deepwater applications under the actual pressure and temperature conditions, ATV has designed and manufactured what it claims is one of the industry’s most advanced hyperbaric chambers, with a 2.5-m (8.2-ft) internal diameter. This can simulate operating conditions of a valve and its actuations, including in large dimensions, in up to 4,500 m (14,764 ft) of water (450 atmospheres).

ATV is producing subsea valves and actuators for the Stampede oil and gas project in the Gulf of Mexico, in a water depth of roughly 3,500 ft (1,100 m). This order is for 9-in. 10,000-psi through conduit gate valves with FSC hydraulic actuator and ROV override, and 9-in. 15,000 psi (1,034 bar) with gear and ROV override. For the ultra-deepwater Julia project in the same sector, the company has developed what it claims is the first high integrity pressure protection system (HIPPS) ever installed in the Gulf of Mexico.

Offshore Angola, ATV will provide large bore high-pressure valves for Total’s Kaombo project in deepwater block 32, in this case subsea ball valves, 10-in. and 12-in. and rated to 7,500 psi (517 bar), featuring hydraulic actuation FSO with ROV override.

Finally, for the ongoing Kashagan development in the Capsian Sea, ATV is supplying conduit gate valves in 6-in. and 18-in. sizes, rated to 10,000 psi and 15,000 psi.
