About Hawle Schweiz Armaturen AG

Hawle Schweiz Armaturen AG, headquartered in Sirnach, is a manufacturer of valves, control valves, fittings, flanges and fittings components for water, gas, wastewater and anergy technology. The ductile raw castings come from the Hawle Group's own foundries in Europe; the finish machining of the raw castings, equipping, assembly and final inspection take place at the Sirnach site. The products receive a corrosion-protective epoxy powder coating using the fluidized bed sintering process; steel components are welded using TIG and MAG processes in accordance with ISO 3834-2. The product range comprises over 5,000 standard articles as well as custom-made products, complemented by services such as valve inspections, hydrant overhauls without pressure interruption, maintenance of Hawido control valves and under-pressure tapping up to 16 bar. Customers include water and gas utilities as well as municipal supply companies in Switzerland and abroad. In addition to its headquarters, the company maintains branches in Eclépens (French-speaking Switzerland) and Camorino (Ticino).
