VARIVENT® and ECOVENT® single-seat valves are used for hygienic applications. The valves are characterized by their ease of operation and flexibility. To avoid pressure surges, individual variants in the VARIVENT® modular system are designed for different flow directions.

In the case of the simple shut-off, there is only one seal in the one-piece valve disc, which separates the pipelines. Therefore, we do not recommend to use single-seat valves for separating "hostile" media. In practical use, these valves are often used as emptying or drainage valves or for shutting off a bypass line. Frequently, these types of valve are also used as dosing valves.
