About Us

A company sign on an office door or on a factory building is often the first visible indication: this is where a new business is established. But actually the business started much earlier: as an idea in the heads of the founders.

Valve and machine actuators – an idea turns into a product. On October 15, the company Riester KG is registered in the trade register of Esslingen. Werner Riester and Rudolf Dinse start the development of the first range of actuators. Robust and reliable – that’s how they should be. Water and sewage treatment plants are the first customers.
