Sistag can look back on over 50 years of history. As a future-oriented family company in the valve industry, that sets international standards with our knife gate valves, water control gates, and butterfly valves, we help our clients to meet challenges in their field with the highest degree of exper- tise and reliability. But we can also count on much deeper roots: in Switzerland, in the USA, and around the world. Our success is due to the values that we live by and in which we believe, values that give our customers security, build trust, and bring clarity – because they embody what our company stands for.
