MV4 - MV14 DBB BALL VALVES
MV4 - MV14 DBB BALL VALVES
  • Established engineered product design, well-known in the industry for subsea, offshore and onshore applications.
  • Offers space and weight saving, compared to the option of two independent ball valves. 
  • Flanged, WE/WE or flangeless design.
  • Selected typically for applications where the customer is looking for more reliability in the seats performing with zero leakage, where common failures occur due to foreign particles in the media. This product with a single body with two balls and four seats offers this increased performance capability.
  • A proven and reliable ball valve design.
  • Manufactured using forged materials in various grades CS, SS, Duplex and all other high alloys ensuring this design can meet all our customers material requirements. 
  • Manual and/or actuated configuration.
  • Engineered products typically having a long lead time delivery of 24 weeks or longer.
  • Available for various industries and applications as shown below.
