Piggable Valves and Manifolds
Pigging systems are composed of piggable valves and manifolds that automate the cleaning and emptying of transfer lines used for material distribution.
Piggable valves and manifolds enable multiple successive product transfers through a single line without contamination. With Emerson?s Pigging systems you can improve safety and efficiency while reducing piping, flushing, and contamination.
