Mixproof Valves

Mix proof valves provide safe separation of dissimilar products within the same valve body.

The W72RS Series Mix Proof valves feature a lower radial seal seat for minimal spillage of products when opening or closing.

Various model offerings are available to meet the processing demands for brewery mix proof applications.

• Bodies machined from solid bar 316L give high strength and stability to endure thermal and mechanical stresses common to breweries.
• 2'' - 6'' (51mm - 152mm) Schedule 5 pipe sizes
• Fully balanced stems available
• External Flush available to clean vent cavity and drain during long product run or when CIP not readily available
• Optional hose barb or clamp connection on the drain port

Mix Proof valves provide safe separation of dissimilar products within the same valve body.

The W71 Series Mix Proof valves feature compression style seats for standard shut-off service that ensure long life and dependability.

W75CP2 for safe separation of dairy product from CIP plus single seat-lift separation compliance. Fully independent operation and cleaning of either the upper or lower housing to maximize plant uptime and capacity while allowing flexibility in cleaning and production runs.

Fully independent operation and cleaning of either the upper or lower housing is achieved due to:

• 3-A sanitary standard 85-02 approval
• PMO Section 15p(B) compliance for single seat lift separation while product is in the opposite housing
• PMO Section 12p compliance for ability to clean all product contact surfaces

Features and Benefits

• Continuous production and cleaning
• Secure and reliable
• Compact and better value
• Completely and easily serviceable
• Robust
