The structure of the VARIVENT® modular system means that different valve configurations (closing direction of the valve disc) and numerous options are available. Please refer to the options section in the catalog for information about these.
Single-seat divert valves: Long-stroke divert valves
DN 25 – DN 150: DN 65 – DN 100
OD 1" – OD 6": OD 2 ½" – OD 4"
To avoid water hammers when closing one path while the product is flowing, single-seat divert valves should be switched against the flow direction of the product if possible.
The single-seat divert valve type W is used for merging products from two pipelines, whereas valve type X has been designed for product distribution. The valves are characterized by their ease of operation.
In practice, these valves are frequently used in CIP supply and return lines. One typical application is also found at the end of a valve block in which the valves are fitted as divert valves between the process line and the drainage (e.g. during pushing out).
VARIVENT® long-stroke valves are used for manufacturing products with relatively large particles or for viscous products, such as strawberry yoghurt.
