LIAG ARC VALVES

Ideal for pasty media and low-germ processes

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.

PIGGING VALVES

Ideal for hygienic pigging processes

LAUFER pigging valves have been designed according to hygienic design guidelines to meet the high demands of process engineering applications. They build upon the same design principle as free flow arc valves. By virtue of this principle no products remain in the valves during operation.

The prime use of LAUFER pigging valves is with sterile pigging systems as they can be disassembled easily and quickly even when welded in place, and additionally, offer high CIP capability.

Applications

Process systems, which can be cleaned with pigs, are becoming increasingly important for the low-germ processes. Among other reasons, this is attributable to an increased environmental consciousness, costly waste water treatment, prevention of costly product losses, and production streamlining measures.

We offer a variety of pigging technologies to satisfy the requirements of the wide range of processes.

Optimum pigging geometry and the suitable process depend on different process factors and are therefore always designed to the specific project:
