What Volz does

Volz Gruppe GmbH is a German family-owned manufacturer of hydraulic connection technology, founded in 1925 in Deilingen on the Swabian Alps and currently led by third-generation owners Dr. Christoph Fleig (Managing Director) and Sigrid Fleig. The company designs and produces tube fittings, hose fittings, adapters, JIC flared fittings, and industrial balls for ball valves in stainless steel (1.4571/316Ti) and carbon steel, offering a catalog of more than 50,000 standard parts alongside bespoke custom-manufactured solutions. Its manufacturing footprint comprises three factories in Deilingen totaling roughly 7,900 sqm with 93+ production machines, plus a wholly-owned machining facility in Wrocław, Poland (Volz Polska Sp. z o. o.) with approximately 50 additional machines and 105 employees.

The business operates a hybrid go-to-market combining a direct enterprise sales force (Senior Global Key Account Managers, regional sales managers) with a global dealer network and wholly-owned regional sales subsidiaries in Australia (Albury, Brisbane, Perth), Singapore, Turkey, and Ukraine. Pricing is quote-based through direct sales channels under AGB terms dated December 2024, with revenue generated almost entirely from one-time hardware sales of standard and custom hydraulic components plus pre-assembly machines. The customer base spans hydraulic system manufacturers, OEMs, ball valve manufacturers, and end-verticals including maritime, chemical, railway, and the emerging hydrogen energy sector. Worldwide headcount stands at approximately 340 employees across manufacturing, sales, and administration.

Volz's competitive position is anchored by vertical integration (in-house development, production, warehousing, and R&D), an extensive batch-traceability system, and a comprehensive set of maritime and industrial certifications including DNV-GL, Lloyd's Register, Bureau Veritas, ABS, RMRS, CCS, AD 2000-Merkblatt W0, ISO 9001:2015, and ISO 14001:2015. The company is also pursuing forward-looking initiatives such as its dedicated Wasserstoff-Programm (Hydrogen Program) for hydrogen energy applications, a recently launched line of O+P pre-assembly machines for cutting rings, and proprietary products including distributor blocks rated to PN 630 bar and a compact compensation rotating fitting rated to PN 420 bar. The firm celebrated its 100th anniversary in July 2025 and remains under Fleig family ownership with no institutional investor backing disclosed.
