Cost Effective Mixproof Valve

Unique mixproof valves feature two independent plugs. This means a single valve can often replace two or more valves of other types, reducing the number of components in the line and simplifying flow management.

Exceptional Spillage Free Operation

A state of the art double seat design provides long lasting, spillage free operation to help minimize the risk of product contamination. Double lip seals provide added protection for safe and hygienic performance.

Easy to Maintain and Clean

Unique mixproof valves feature a top loaded design that makes maintenance fast and practical. With no adjustable components, a maintenance friendly actuator, and built in leakage detection on all seals, the valve concept supports reliable hygienic operation. For tougher cleaning needs, the valve can be supplied with the optional SpiralClean cleaning system.

Valve Clusters, Customized Flow Solutions

We specialize in supplying pre built valve clusters customized to meet specific process requirements. Our expertise helps ensure efficient flow management using as few components as possible while addressing thermal cycling, cleanability, drainability, and flow control.

Valve clusters can be supplied pre assembled and pre tested, and can also be delivered fully wired with pneumatic tubing, junction boxes, and control panels pre connected. This helps bring complex installations online faster and reduces downtime risk from on site troubleshooting.
