Model HM Type - Pigging Valve Brochure

HARTMANN VALVES pigging ball valves of the HM series combine the advantages of the HARTMANN VALVES AST series, and in addition to classic applications function as shut-off valves for pigging insertion or removal valves. The simple, secure, and fast insertion and removal of pigs takes place through an interlock that is integrated on the side of the pigging ball valve and that is locked and secured through a bayonet system.
