Butterfly valves have been a key system component in the hygiene industry for decades. They were developed, designed and manufactured for installation in pipelines for shutting off a flow of liquid. Suitable flow media include water, steam, petroleum, food, liquids in the chemical and pharmaceutical industry and pasty media.
AWH butterfly valves represent maximum quality, reliability and hygiene. The butterfly valves are supplemented with a comprehensive range of accessories, and therefore offer the ideal solution for every application. In addition to a range of manual operations, the valves can easily be equipped with pneumatic or electric drives. A wide range of initiators and control heads are available to monitor performance. A clear advantage of AWH butterfly valves are the bearing bushes which minimise the wear on the axle, making our valves very durable. Of course, we also provide you with all standard approvals and test certificates for the materials used, such as EHEDG, ATEX, APZ 3.1. to DIN EN 10204, FDA and EC regulation 1935/2004.
The semi-finished products we use are sourced from Western European stainless steel forges and have material certificates. The butterfly valves are manufactured exclusively in our headquarters in H?tensleben. They are subject to a continuous quality control process, which allows us to guarantee constant and consistently high quality. If you have questions on our product range, the AWH team will be happy to provide you with help and advice.
