Fully welded ball valve

Fully welded ball valve introduction

Fully Welded Ball Valves, trunnion mounted, for onshore and offshore topside applications in the Oil & Gas transmission.
Fully welded ball valve offers the advantage of a compact envelope, which allows for increased strength and significant reduction in weight. Furthermore, since the body is made by welding forged parts, there are fewer potential leak paths when compared to side-entry and top-entry ball valves.
Fully welded ball valve is in a wide range of materials and configurations to meet any specific need of the application and customer’s requirements. Many optional features are available for seat designs, seat and stem seals, and end connections. 
Fully welded ball valves are suitable for manual operation or for power assisted operation. Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (API, ASTM, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.  
Fully Welded Ball Valves comply with ISO 14313 requirements and with all the relevant Industry standards and codes (ANSI, API, ASME, BS, ISO, NACE, PED and others). The weldings of the body are perfomed and qualified according to ASME Section IX; non-destructive examinations (NDE) are performed in compliance with ASME VIII Division 1 and 2.
