MV5 FULLY-WELDED BALL VALVES API6D
MV5 FULLY-WELDED BALL VALVES API6D
API 6D - API 6DSS
  • Established product design, well-known in the pipeline industry.
  • Offers a reduced overall weight, especially in larger sizes 24" and above with the welded ends.
  • Manufactured with forged materials in the various grades of CS, SS, Duplex and all other high alloys, thus ensuring this design can meet all our customers material requirements. 
  • Compact body design available in large sizes 24" and above, with weld end/weld end connections.
  • Alternative option to the side-entry bolted body (MV3) for specific design applications.
  • Typically used in underground service gas transmission pipelines or subsea. These are the most commonly used applications.
  • The body is welded together, if repairs are required, it is a major exercise, which can only be performed at manufacturer's plant. 
  • Suitable for various industries and applications as shown below.
