Weighing approximately 90 kilograms and with a nominal diameter of DN 150/200, this newly manufactured N1 Mixproof Valve is exceptionally large.

The valve was specifically designed and manufactured to meet a customer’s requirements. It will be used in the beverage industry for water distribution. The housing is made of solid material, and the valve is additionally equipped with a seat relief mechanism.

The sheer size of this custom design is already evident during in-plant transport: a crane is required for safe lifting and packaging.

This project demonstrates how RIEGER turns specific requirements into a custom-fit valve solution—precisely manufactured and tailored to each individual application.
