Gas pressure control using a VARIVENT® modulating control valve type A and type S (upon request) with power supply.
- The switching module regulates the aeration and degassing independently from the operation and process parameters.
- The path to the cleaning devices via the VARIVENT® butterfly valve is closed.
- The switching of the paths happens pneumatically.
- Then the path to the cleaning devices is open and the aeration and degassing path is closed.
- The switching module is suitable for high gas currents.
- The modulating control valve can be individually configured from the VARIVENT® valve programme.
