Multiport Valves

Multiport valve blocks are often installed when complex solutions in process engineering systems are required. Compared with welded designs, these valves require minimal space and are optimised to prevent deadleg.

The compact design of the valve seats significantly reduces the size of the area that comes into contact with the media in a multiport valve block compared to a conventional welded or ring design. A smaller fluid chamber means less risk of contamination and can also considerably reduce product loss and plant size.

Our multiport valve blocks are entirely custom-made according to your specific requirements.

Project support

We manufacture our multiport valves on a customer-specific basis and accompany our customers from the initial enquiry to the implementation of their projects.

We provide support as early as the planning stage with ideas and initial design drafts. We then create 3D models in close consultation with our customers. The final design is manufactured in our own production facilities using state-of-the-art technology and in accordance with the high requirements of our customers.

Design Overview

The production of individual and customised multiport valves is one of our core areas of expertise.

Here you will find a small selection from the large variety of multiport valves already created by us.

Further designs are of course possible!
