LIAG® Pig Diverter
Arc Valve

Ideal for hygienic pigging processes

LIAG® pig diverter arc valves are 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 product remains in the valves during operation.

The prime use of LIAG® pig diverter arc 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.
