Roediger Vacuum Valve Units

On this page more_vert

The collection chamber houses the Roediger vacuum valve unit. This unit consists of the vacuum valve and an associated controller. 
These units do not require electrical power because they are activated pneumatically, depending on the filling level of the collection sump.

Unique Features

The Roediger vacuum valves are distinguished by their durability, their universal application and their simplicity in operation and maintenance. In order to respond to customer requests and project-specific requirements 3 different valve types are available: 50 mm, 65 mm and 75 mm.


The Roediger compact controller has the task of opening the vacuum valve as soon as the level of wastewater in the sump of the collection chamber has reached a certain level and not to close the valve again after the batch volume and preset amount of air have been evacuated from the sump. The controller can be adjusted to allow for optimum valve opening times and air-liquid ratios.
