24h of valve making

24h of valve making

A normal working day has not enough hours to produce all the valves we need. That’s why we work in three shifts. Every evening our production team programms the automated manufacturing system to run the night shift on its own. For eight hours the system keeps milling standard valve bodys that are controlled and further worked on in the morning. More complex or customized solutions still need the watchful eyes and handicraft skills of our employees and are therefore made during the day.

Equal Pay

Sistag is a certified employer with equal pay for men and women. The equal treatment of our employees, regardless of gender, age or nationality, has always been important for us. We are therefore very proud that our equal pay policy has now been officially certified.
