C 8686


Wafer type valve in short face-to face dimension DN 50 – DN 500: PN 10


Product advantages

High serviceability
easy exchange of wearing parts

Easy installation
a holding lug is attached to the upper part of the check valve which allows better installation of the valve

Space saving
due to short face-to-face dimension

Sandwich design

Variable installation position
the check valve can be installed vertically (only with flow direction rising from below) or horizontally

Universal use
in all areas of process technology

Electrically conductive
no expensive antistatic device necessary

High reliability
Backflow is reliably prevented. Compared to conventional valves in flanged design the weight is much lower and the length much shorter

Long service life
due to the simple, robust design
