They lock, control, dose – safely and reliably. We have the matching valves for any application: Our product range from DN 15 to DN 200 includes both standard fittings as well as process-dependent optimised products. For instance, ball valves, diaphragm valves, butterfly valves, check valves and solenoid valves. They are elementary parts for plant engineering projects, and we have them under our control. Maximum resistance, minimum wear – this is what STÜBBE's valves stand for.
