Butterfly valves SV

A wide range 

From a small dosing line through to large header tubes, with the hygienic butterfly valves from Guth you can cover all applications from a single source. We offer a wide range of options for this. A comprehensive drive and accessory program for the task-specific operation and automation of shut-off, changeover and regulating functions completes the range. Our own DIN and imperial series ensure that everything fits perfectly together.

- Sandwich design for higher pressures
- water-tight control head with modular construction and no-tool assembly for particularly tough conditions
