BOHMER STANDARD FOR SUBSEA APPLICATION - AN OVERVIEW Each single valve is the product of more than sixty years of experience. This experience enables us to produce ball valves that are more than adequate of the strong requirements of the subsea industry. The fully welded design eliminates potential leakages to the outside. The material of the sealings as well as of the components in touch with the medium is chosen to fulfill the highest demands. This way a long service life is given while the valves are absolutely maintenance free. No wonder B5hmer is one of the few manufacturers with API...

Applications: • Pipeline End Manifold (PLEM) • Subsea Oil- and gas pipelines • Jacket Flooding Systems • Hot tapping subsea • On- and offshore platforms • Shipbuilding (FPSO storage tanks) • Special applications Optional features: • Body material duplex • Trim material duplex • CRA overlay (SS316 or Inconel 625) for seat ring area, seat pockets or complete passage • Metal to metal sealing • Drain valve with pressure tight cap • Lip Sealings

PRECISELY DESIGNED AND PROVEN IN THE FIELD Bohmer fully welded subsea ball valves fulfill the requirements of the most common national and international standards. BASIC DESIGN FEATURES Seat Seal System The Bohmer ball valves provide spring supported seats as a standard. The seats are pressed against the ball surface by the spring elements and ensure a tight shut-off at low line pressure. In addition the sealing effect is assisted by the pressure in line. So the total sealing force is the sum of the spring force and the force resulting from the pressure which increases proportionally with...

Double Block and Bleed The cavity can be relieved via vent or drain connections at the cavity. The upstream and downstream seat rings ensure the tight shut off to the cavity in closed position (optional in open position as well). This enables the verification of the tightness of the ball valve under full working pressure. Single-Piston-Effect (Self-relieving Seat Design) This seat system is designed to automatically vent any excessive build-up pressure in the body cavity. The floating seat design allows for relieving the overpressure into the pipeline. ➀ Body ➁ Ball ➂ Stem ➃ Trunnion ➄...
