Inline Equipment

In the current process technology, fixed piping systems lead to permanently closed systems within the single plants which do not allow the operator to have a direct view into the production process. By equipping the pipelines with VARINLINE® housings, control and measurement instruments can be installed within the piping systems to monitor the production process.

Sampling Valve, type TSVN

The valve disk closes the product pipe from the outside (type N) or from the inside (type U).

Sample drawing may be automatically or manually via a one-port or two-port process connection. Optionally, the valve stem sealing may be reinforced by a metal bellows. Position feedback is available on request.
