Bellows Valves for Bulk Gas Delivery

Kitz SCT IBC/IBD/IBE series product.

Bellows Valves for Bulk Gas Delivery

The IBC, IBD, IBE series, like the SBB series, consists of larger pipe size bellows valves that have a compact design compared to other bellows valves. They provide a high Cv value and the durability needed for supply lines.
  • KITZ SCT’s Y shape structure yields higher Cv than conventional S shape structure.
  • The inner surfaces of the IBC/IBD valves are uniformly polished whole-surface cylindrical grinding.
  • Because of their screw-sleeve structure with built-in bearing, the IBE valves require less torque on the handle for easy operation.
  • Adopted a seat structure to reduce gas pooling and particle shedding.
  • By setting the air supply inlet on the top of the actuator, there is no concern over piping direction.
  • Realization of more compact design through positioning the actuator on the side.
  • Purge port options available for the Inlet, Outlet, or Both.
  • SCS16A, SCS16A (125A~150A), SUS316L (200A~300A)
  • IBC/IBD/IBE Series cannot be used with reactive or corrosive gases, nor with any liquids.
  • These valves are designed to be used under atmospheric pressure. Usage such as under vacuum vessels is not guaranteed.
