Special valves & tank safety systems

VARINLINE® Sampling valves

These valves are used for taking random samples for monitoring the biological condition of product lines. Suitable products: media without suspended particles and of low viscosity, e.g. water, beer, milk, juices without fruit pulp.

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.
