W72RS Series - Double Seat Mixproof Minimal Spill Valves

Features & Benefits

Mix Proof valves provide safe separation of dissimilar products within the same valve body. The W72RS Series features a radial seal seat design for minimal spillage of products when opening and closing.

Safe, Continuous Production and Cleaning:

• Proven mix proof valve design allows plants to maximize production and minimize downtime for cleaning
• Radial seal (RS) design on lower stem minimizes spillage of product to drain during opening and closing for critical product applications in highly sanitary environments
• Full mix proof model portfolio for completely automated systems:
  • W72RS shut-off for safe separation in the fail-closed position
  • W72RSP shut-off for products containing large particulates (up to 1.25” (32 mm) diameter)
  • W72RS tank outlet version for safe separation between tank and servicing pipeline

Robust and Durable:

• Compression seat design on upper stem provides long seat life and reliability
• WCB’s signature machined-from-bar bodies and components offer a robust and reliable valve solution
• Consistently thick body wall dimensions & laser welded port extensions minimize body distortion during manifolding & extreme fluid temperature changes
• Balanced design for resistance to hydraulic shock

Flexibility and Modularity:

• True-line mix body sizes and custom 45° or other angled ports available to match complicated pipe design
• Custom port lengths and center-to-center dimensions can match competitor and legacy series valves to provide easy drop-in replacements
• AL6XN alloy product zone parts available for corrosive products
• Various control top models available to fit customer needs: cost-effective CU4, full-featured robust WCB control tops, or state-of-the-art Burkert 8681
• Choice of adapter options with stem flush, wiping stem seals, and steam sterilization

Low Cost of Ownership with Easy Maintenance:

• Heavy-duty construction maximizes service life
• Minimum propriety parts give off-the-shelf availability and low price of most spares and tools
• Long-life actuator is field-maintainable with finger-safe, caged springs and cartridge piston assemblies
• Simple, easy-to-maintain design is intuitive and does not require advanced mechanical skills
• Compressed air not required for disassembly, maintenance, or assembly procedures after removal from body
• With quick-disconnect pin connectors, control top can remain on valve during disassembly & maintenance. No added steps for removal or operator exposure to electrical controls.
• Adjustable seat clean travel allows users to optimize CIP flush going to drain
• External flush connections are stationary allowing hard piping of utilities and no pinch points
