VARIVENT® DIVERT VALVES

Function
Single-seat switch valves are suitable for separating and distributing fluids. There is only one seal for each switching rod in the valve disc, which separates the respective pipelines from one another. Single-seat switching valves are therefore not suitable for separating incompatible fluids.

Special Features
  • Certified, hygienic configuration
  • Metallic stop
  • Flexibility because of the modular principle
  • Proven seal geometry

VARIVENT® series

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.

Recommended Flow Direction

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.



Application Examples

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.
