Hygienic Valves Overview Hygienic valves Sealing according to the VARIVENT® principle VARIVENT® and ECOVENT® hygienic valves offer reliable function, are suitable for CIP / SIP, easy to maintain and represent a significant factor in consistent product quality. Low operating, maintenance and servicing costs ensure economical system productivity. The hygienic valves are characterized by special seal technology. A metallic stop results in defined seal deformation, ensuring long seal life. This allows for more time to pass between required maintenance services with the process system, thereby allowing...

Hygienic Valves Overview The VARIVENT® modular system 1 Control and feedback system The high flexibility in the VARIVENT® system offers many advantages. With the ability to combine all basic elements with one another, the system offers a broad range of possible applications. Existing valve systems in process installations can be modified or adapted without changing the current system concept. Both variants of the T.VIS® generation offer the opportunity of selecting between two feedback systems variably depending on the customer requirements. Whether the proven sensor technology in the T.VIS®...

Hygienic Valves Technical Data Materials Housing connections Components in contact with the product are produced from 1.4404 / AISI 316 L, while those not in contact with the product use 1.4301 / AISI 304. Other materials, e.g. for use when handling aggressive fluids, are available on request. Two alternative housing connections are available: the clamped connection (standard) and the fixed housing connection. The clamped housing selection permits a flexible choice of port orientation. For detailed information about the properties of the materials, refer to the material properties table (see...

Hygienic Valves Technical Data Ambient conditions Operating pressure Ambient temperatures VARIVENT® / ECOVENT® (with T.VIS® control module) Proximity switches The valves can also be used outdoors. However, in these application areas they must be protected against icing, or else deiced before switching or lifting. In addition, the particular requirements on the control and feedback system must be taken into account in this case. The product or operating temperature depends on the seal material and can be seen in the seal material properties table (see page 15). Installation VARIVENT® and ECOVENT®...
