ATEX-certified valves


(please click the picture for the pdf download)

With RIEGER valves, you have the flexibility to use them in potentially explosive atmospheres (ATEX area) as well.
The ATEX directive defines an explosive atmosphere as a "mixture of
flammable substances in the form of gases, vapors, mists or dusts
and air under atmospheric conditions, in which the combustion
process, after ignition, transfers to the entire unburnt mixture
(Source: "Guideline 2014/34 / EU").

Our hygienic and especially the aseptic valves are used not only in
the pharmaceutical and food industry, but also in biotechnology and
fine chemicals.

You can do a first check, whether our valve is suitable for your
application with the flowchart aside.

We are happy to provide you with a quote for your ATEX valve if the
rating of our valves "Ex II 2GD c IIAIIB max. 135C X "* fulfills your

(Here is an example of the N4 piggable double seal valve- for 150°C
short time SIP.) . Simply send us your inquiry via our form.

* The Ex approval is only valid if the valves are purchased as a complete product from the manufacturer.

Be sure with RIEGER - The safety of our customers is
top priority for RIEGER.
