GEA Tuchenhagen VARIVENT® Sanitary Seat and Mixproof Valves

The VARIVENT® system is a flexible modular system and therefore offers many advantages, for instance standardized parts interchangeable with various valve types.

The result: cost-effectiveness for the plant owner, optimized stock-keeping, favorably-priced spare parts and low parts diversity.

VARIVENT® sanitary valves are characterized by their special sealing technique. The metallic stop of the valve disk ensures defined deformation of the seal which provides a long service life, short downtimes and continuous production.

GEA Tuchenhagen 24/7 PMO Mixproof Valves

The GEA Tuchenhagen 24/7 PMO Valve™ has been designed to allow safe separation of non compatible products (such as milk or milk products & cleaning solution) and is approved by the FDA (through the issuance of Memorandum M-b-353) to allow one housing of the valve and the corresponding valve seat as well as the vent cavity to be cleaned while milk or milk products are present in the opposite valve housing and line.

In process system designs which utilize the 24/7 PMO Valve™, the processor will greatly increase the throughput of the process system. This is due to the elimination of the downtime required by all other single seat and mixproof valves systems where the process operations must be shutdown for valve and manifold cleaning.

In the case of PMO Mixproof valve or double-block-and-vent single-seat valve systems, PMO regulations have UP TO NOW not allowed the cleaning of the vent cavity or a valve seat while Milk or Milk products are present in the valve under item 15p (B) section (6) of the PMO. This vent cavity cleaning restriction has been lifted for this 24/7 PMO Valve™ alone.
