Non-Return Valves

The Guth non-return valve has been designed

to prevent reverse flow of fluids in pipe systems

in all process applications.

The design of the seal chamber is similar to

the sealing principle of the aseptic standard

DIN 11864 (see explanation on next page).

Thus, the risk of getting product behind the

seal is minimized. Thanks to the hygienic design

of the seal and the special inner surface design

the valve can be cleaned easily and effectively.

This makes the valve particularly suitable for

all process applications with higher hygienic

requirements like in the food & beverages or

the pharmaceutical industry.

The Guth non-return valve is available in

AISI 304 (1.4301) and AISI 316L (1.4404)

stainless steel.
