What KLINGER Holding does

KLINGER Holding GmbH is a privately held Austrian industrial group founded in 1886 and headquartered in Gumpoldskirchen. The company designs and manufactures industrial sealing products (sheet materials, gaskets, seals in CNAF, PTFE, graphite, metallic, and elastomer formats), fluid control components (ball, butterfly, piston, gate, globe, check, plug, diaphragm, safety, bellow seal, and control valves spanning DN 10 to DN 3000), fluid monitoring instrumentation, expansion joints, and hoses. It also operates proprietary engineering software — KLINGER Expert, IntegrityXpert, and KemProof — for gasket calculation, integrity management, and sealing verification.

The group serves process-industry customers across oil and gas, energy, chemical, mining, pulp and paper, marine, food, and other sectors, with disclosed reference customers spanning Wien Energie, Vale, Grupa Azoty, Sitech, ELG, Tereos, Abengoa, Solatom, S. Spitz, and Sunpor. Operations span 93 locations across 60 countries with 18 production sites, supported by 3,100+ employees and €719 million in annual sales.

KLINGER's revenue model combines direct sales through owned subsidiaries, indirect sales via channel partners and resellers, and e-commerce; pricing is quote-based, anchored to multi-year contracts and project specifications. Revenue streams comprise one-time product sales, recurring software subscriptions, professional services (leak detection, shutdown services, steam audits, emissions audits, training), and international logistics. Recent commercial emphasis has been on control-valve portfolio expansion (via the 2025 Conovalve acquisition) and energy/mining verticals in South America (Chile 2024, Uruguay 2026).
