The DEFINOX tank bottom changeover valve possesses the same qualities as DCX3 changeover valves (floating seal, extra-thick body, strength,...). It differs however by the shape of the body and plug forming a seal tight up to the tank bottom. Automatic and manual versions are available, as well as a choice of raising or lowering plug.

This valve can be equipped with a long-stroke actuator for total plug clearance and reduced pressure drop.This version is particularly recommended for fragile or heterogeneous products.
