To accommodate the different requirements of various industries, applications and processes, we have a variety of mixproof shut-off valves in our portfolio.

VARIVENT® double-seat valves are used for mixproof shut-off of incompatible products at pipe junctions.

A special feature of this valve is that one of the valve housings may be pushed out using a pig. This technique allows for the recovery of high quality products at the end of a process step and thus to minimize product residues inside the pipe.

VARIVENT® mixproof valves type C and K are used as an efficient alternative for mixproof separation of incompatible products at pipeline junctions within CIP systems or gas blocks.
