The customer determines our success Times are changing, structures are changing but there is one thing that has not changed: our customers are our focus and the center of our business they determine the success of our business. Based on this we believe we strive to manufacture sound technical products of the highest quality and have been doing so for more than 150 years. To meet this standard today and in the future we work according to modern design and manufacturing principles. Our Quality Management System ensures that our products meet the highest quality and hygienic standards. In 1998 we were certified according to DIN EN ISO 9001 and are audited regularly by a third party. In order for us to maintain this quality of workmanship we ensure that we support our employees in all business areas with internal and external training. The Guth Quality Management System is certified since 1998 and is audited regular by a third party. 2

Customer requirements are met through the manufacturing of customer specific components Custom products for our customers Application knowhow for you The Guth Training Center Customer s individual needs are also met. We regularly manufacture individual components to meet the customer s specific requirements that are still of the same high quality as our standard line products. Our flexible structure allows us to process your orders reliably and on time, this also means that we can offer professional advice and service. Our close relationship with our customers is shown in our Guth Training Center. Here the operation of process valves is communicated to customers, employees and sales partners. Application minded seminars are frequently held for training purposes. The Training Center offers a modern environment with work stations and product installations. We are more than pleased to train you or your employees in functional operation, design and optimizing of processes, as well as redesign and maintenance and service!
