Standardization of the WEH® Check Valve range

As a leading manufacturer of components for fluid handling, WEH offers an extensive range of high-performance check valves. Now this extensive product range is being standardized.

Starting with stainless steel check valves for strict requirements, steel and brass check valves as cost-effective alternatives down to special solutions developed according to individual customer requirements, WEH offers the right check valve for nearly every purpose of use.

What is new?
The standardization of the product range offers important advantages. With the introduction of product families and product series, the entire product range has been restructured.
This has made it possible to optimize processes internally and reduce the variety of components required.
The benefits for you: Improved delivery performance for WEH® Check Valves.

To guarantee optimal transparency during the procurement of WEH® Check Valves, the Availability of the individual check vales is now indicated in the catalog.
The availability for product variants is subdivided into WEH® Ready-Made (warehouse items) and WEH® At-Hand (individually configured product variants).
