Guth butterfly valves

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.

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

• Forged, flow-optimised, low-wear disc contour with a highly polished surface for optimum hygiene conditions and high pressure resistance

• Forged, robust housing in certified stainless steels with pore-free surface for safe assembly

• Robust, durable and ergonomically optimised manual mechanisms in stainless steel

• Generously dimensioned, extremely durable and proven precision drives made of stainless steel in different sizes, single or double-acting

• Also available as a multi-way valve in 2-/3-way design
