Integrated production system

Production systems that ensure high quality

“When cutomer needs them”,“In the quantities customer needs”,“With better quality”.

KITZ Group manufacturing is based on delivering the products customers need “when cutomer needs them”, “in the quantities customer needs” and “with better quality”.
Based on integrated manufacturing, KITZ positions castings (bare metal), the valve material, as its core technology and manufactures them in-house from the casting stage.
Integrated production, with casting facilities for each of the main valve materials – bronze, cast iron, ductile steel, stainless steel and cast steel – within the group, has enabled us to establish a quality assurance system based on materials and to achieve high-mix, low-volume production.
