ATV - Subsea Swing Check Valve

The swing check valves can be regular port or full port, this latter being the option when the valve shall be piggable having an optimized design of body cavity and flapper.

ATV Swing Check valves can be supplied with clapper lifting device operated by a ROV tool (or by diver in shallow water). Lost motion devices can be supplied to reduce the wear on the shafted seals. Sensors for remote indication of clapper position are also available.

ATV supplies the subsea swing check valves in a wide range of materials and configurations to meet any specific need of the application and customer’s requirements.  ATV valves are manufactured with hardfaced sealing surfaces with cobalt-chromium alloys. Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.

ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (API, ANSI, ASME, DNV, BS, ISO, NACE, PED and others). 

ATV stresses its willingness to produce engineered valves; therefore, it welcomes requests for special size, class and design requirements.
