Persta

What Persta does

PERSTA Stahl-Armaturen GmbH is a German manufacturer of high-pressure forged-steel industrial valves, founded in 1946 as a subsidiary of the SIEPMANN-WERKE group (with forge heritage dating to 1891). The company is headquartered in Warstein, Germany, with its production facility in Olfen. Its core product portfolio spans globe valves (PN 10–500), gate valves, check valves, stop-check valves, blow-down valves, overpressure safety devices, pneumatic actuators, and pressure test plugs, plus a Smart Valve Monitoring System add-on for IoT-enabled predictive maintenance.

PERSTA's production is differentiated by its in-house forged-steel process (drawing on the parent SIEPMANN-WERKE forge) and an in-house welding engineering team, which the company uses to avoid casting defects and to serve safety-critical applications. A 2011 majority acquisition of SD MACHINING GmbH vertically integrated mechanical processing into the production chain. The company distributes through regional sales representatives in Germany and through international representatives and trading partners globally, complemented by a 24-hour emergency service hotline and on-site/in-house service training.

The company monetizes primarily through one-time sales of high-pressure valves and accessories (nuclear, fossil power, chemical/petrochemical, water/wastewater, biomass, paper, waste incineration, shipbuilding) and through professional services (custom engineering, service, and maintenance). Pricing is quote-based via direct sales with no public list pricing. PERSTA is privately held, family-controlled under the SIEPMANN GROUP, and managed by Managing Partner Korinna Schwittay with an advisory board chaired by Nicolai Siepmann. The company operates a wholly-owned trading subsidiary (VALTRA GmbH, est. 1980) to round out its valve portfolio with third-party brands.
