About WESA-Armaturen
Since 1978, WESA-Armaturen GmbH has been developing, manufacturing and refining ball valves, heating and industrial valves as well as butterfly valves for opening, closing and regulating pipelines. The family-run company with more than 70 employees is based in Winterbach near Stuttgart and has more than 8.000 m² of floor space in Germany as well as numerous production partnerships worldwide. The product range includes brass, stainless steel, high-pressure, cast, stacked and DVGW-certified valves in materials such as brass CW614N/CW617N, stainless steel AISI 304/316, carbon steel 1.0737, spheroidal graphite iron GGG40, grey cast iron GG25 and gunmetal RG5. In addition to series production of standard valves, WESA realizes custom-made products according to customer specifications including drawing creation and 3D STEP files, assembles customer-specific kits and assemblies, and automates valves with pneumatic or electric actuators. In-house assembly teams handle final assembly, reworking and quality control. Customers include the sanitary and heating wholesale trade in Central Europe as well as OEMs from plant engineering, the energy, automotive and food industries, mechanical engineering, district heating stations, renewable energies, environmental technology and paper production.
