Eugen Seitz AG is an independent, family-owned company with more than 50 years of history. Since 1958, we have been developing, producing and distributing premium valve technology all over the world for the technically demanding solenoid valve market from our head office in Wetzikon, Switzerland.

Our primary focus is on developing solutions for gaseous media in the medium and high- pressure range of 16 to 1,000 bar.

Innovative Excellence

Our daily activities are driven by our desire to provide the leading solenoid valve technology for selected industries. Thanks to our activities in research and development, we have extensive expertise in electromagnetic development, actuator engineering, mechatronics, sealing technology, materials technology and explosion protection.

Whether it be new developments or optimisations, our expertise in calculation and simulation ensures a purposeful development process. We simulate valve components in relation to flow mechanics, structural dynamics and temperature fields based on the finite element method. Entire systems are also displayed virtually.

Excellent Valves have a Swiss Origin

Reliability is second Nature to us

100% Swiss Engineering – 100% Swiss-made.

We take care of the entire process, from development through to production, under one roof. This allows us to systematically monitor our processes and ensure quality and adherence to deadlines.

Acting quickly and flexibly

We understand what is important to you and can identify specific requirements quickly. With an excellent knowledge of customer systems, we can provide added value to our clients. Over the course of the project, you have a skilled and solution-oriented point of contact who understands you.

We work purposefully by your side in the development of new products. Thanks to our clear structures, projects are carried out efficiently, methodically and with a streamlined organisation. We handle customer feedback in a straightforward manner and in a short period of time.
