LIAG DMV Pigging System

LIAG® DMV Pigging System

Pigging System

Sterile processes pose stringent demands on system components

For this processes we offer DMV pigging systems featuring CIP/SIP LIAG® free flow arc- and pigging valves and specifically designed pig launching and receiving stations without dead pockets. Simplifying the modular component design, thread and clamp unions are virtually no longer needed, minimizing typical hygienic risk areas by design. All LIAG® arc valves, even when welded in place, can be easily disassembled for maintenance.

Technical Specifications

DMV lip pig – reliable tight

DMV lip pigs are of homogeneous construction (hygienic design). They offer excellent cleaning effect and are virtually free of wear. Dynamic lips form a reliable sealing. As a function of the pushing and counterpressure these lips accommodate perfectly, thereby compensating existing deviations in the pipe geometry. The pigs are highly flexible and suited for tight radii (R = 1,5 x D). As an option, dynamic lip pigs are equipped with a magnet for location and control. They are FDA-rated and available in silicone in the nominal widths DN 40 – 100 (1,5″ – 4″).
