Welland & Tuxhorn

What Welland & Tuxhorn does

Welland & Tuxhorn AG is a privately held German specialty manufacturer founded in 1901 and headquartered in Bielefeld, Germany. The company designs and produces custom special control valves (Spezial-Regelventile) and actuators for power generation, with core products spanning steam conditioning valves, boiler feedwater and boiler steam control valves, steam turbine control valves, balance-of-plant valves, nuclear-certified valves, and hydraulic, pneumatic, and electric actuators. Its technical foundation includes proprietary steam conditioning technology jointly developed with Siemens in 1951, in-house CFD/FEM numerical simulation capabilities adopted in 2012, and active participation in high-temperature research programs targeting 725°C steam operation. The business sells primarily to EPC contractors, boiler manufacturers, pipeline builders, and turbine manufacturers serving conventional, nuclear, combined cycle, solar thermal, biomass, and waste-to-energy power plants worldwide, with components installed in more than 9,000 plants across all continents.

The company operates a vertically integrated manufacturing footprint of approximately 6,800 m² in Bielefeld, employing around 100 production staff plus 10 apprentices, alongside specialized R&D, hydraulics, quality assurance, purchasing, project management, and technical documentation teams. Revenue is generated primarily through one-time sales of engineered-to-order valves and actuators, supplemented by recurring service revenue from spare parts, maintenance, and worldwide on-site inspections delivered through a dedicated service organization with specially equipped vehicles. GTM is direct enterprise field sales via headquarters account teams and regional representatives in Germany (Schildow for North/East; Winterrieden for South), supported by a 24/7 customer hotline. Pricing is not publicly disclosed as solutions are custom-engineered per specification. Certification stack includes ASME N (nuclear), KTA 1401, AVS D 100.50, ISO 9001:2015, PED 2014/68/EC, AD 2000 HP0, EN ISO 3834-2, and a China special equipment production license.

Broad incumbents

• Emerson Electric (Fisher Controls): Global automation leader whose Fisher brand is the dominant control valve supplier worldwide. Broader portfolio spanning process automation, software, and instrumentation, but the Fisher control valve line directly competes with Welland & Tuxhorn in fossil and combined-cycle power plants.
• Crane Co. (Crane ChemPharma & Energy): US diversified industrial manufacturer with a significant process valve business targeting power, chemical, and general industrial customers. Overlaps with Welland & Tuxhorn in severe-service and high-pressure valve applications while offering a much broader product portfolio.
• Flowserve Corporation: US-listed major industrial flow control company manufacturing pumps, valves, and seals for power, oil & gas, and chemical sectors. Competes with Welland & Tuxhorn in power plant control valves while operating at significantly larger scale with broader geographic reach.
• Pentair plc (Flow Control): Global water and flow control solutions provider with industrial valves, pumps, and treatment systems for power, oil & gas, and chemical applications. Broad incumbent serving similar end markets through a wider product portfolio rather than specializing in power-plant control valves.
