Axial On-Off Valves

  • On-off valves are used in particularly critical situations during start-up and station blowdown.
  • Designed for upstream use, they feature short reaction times.
  • Particularly compared to ball valves and gate valves, BOMAFA on-off valves represent a convincing alternative.
BOMAFA on-off valves are manufactured according to customer specifications. Because of the axial flow in the enlarged valve body, the streamlined flow channel prevents turbulence and vibration. In particular, it is possible to open the valve even against a full pressure differential.

Further Advantages

  • weight reduction of up to 60% compared to ball and gate valves
  • rapid valve operation
  • process shut-off due to a particularly ‘active’ sealing technology
