Arc Valves

Fields of applications

LIAG® arc valves have been designed to meet the high demands of process engineering applications. LIAG® arc valves are particularly suited for viscous/pasty products and fluids containing solid particles on account of a totally clear passage, as well as easy and thorough cleaning in place.

This valve series thus provides optimum conditions for a wide variety of pigging system applications. By virtue of their simplicity of design and minimum number of components and wearing parts, arc valves are characterized by high hygiene, low maintenance and safe operation.
