Hygiene shut-off valves ESV

RIEGER ESV hygienic single-seat valves are used whenever maximum productivity, safety and quality are required. They can be found in plants in the dairy industry, the food industry, the pharmaceutical and chemical industries and biotechnology.

The advanced valve concept, proven a thousand times over in daily use, guarantees a high degree of flexibility within the individual series. RIEGER ESV hygienic single-seat valves guarantee our customers the perfect problem solution for their liquid products.

Thanks to the modular system, the conversion from hygienic to aseptic design, from “air-opening” to “air-closing” is possible without any problems. The dimensions can also be adapted to the conditions on site.
