Housing Combinations

?

Shut-off Valves

Mixproof shut-off valves are used to keep incompatible products from mixing at pipe junctions, or to simply shut flow from an upper to lower line within a valve matrix.

Divert Valves

Mixproof divert valves are used for distributing liquid from one pipeline into two others (or vice versa)
