The family business started as a die forge in 1891 and was run by the brothers Emil and Hugo Siepmann. Emil and Hugo subsequently bought out their brother-in-law and shareholder, Louis Peters. In 1946 Stahl-Armaturen PERSTA GmbH was founded with the aim of manufacturing and marketing high-pressure steel valves for industrial applications. Thanks to the reputation and support of the SIEPMANN forge, PERSTA was soon a successful supplier of steel technology. VALTRA GmbH was created in 1980 as a trading company to supply valves from other manufactures. This enabled us to offer our customers complete solutions for all their valve requirements.
Under the leadership of the third generation of the family, the future course was set by investments in highly automated CNC machining technology and a cutting edge automated die forging technique. The technology strategy was completed with the purchase of a majority shareholding in SD MACHINING GmbH in 2011,
a company specialising in mechanical processing. Today‘s fourth generation of the family represents the sustainability and enhanced customer orientation of the SIEPMANN GROUP. An active change management programme was implemented to respond to the technical and commercial demands of our customers.
