TK01
The TK01 is an eccentric, non-return check valve manufactured in accordance with DIN face to face length EN 558/ISO 5752 series 14. When the butterfly valve opens and closes, the eccentrically mounted valve disc swings in and out at an optimal angle. Unlike conventional check valves, the TK is very free-moving and opens with minimal differential pressure. This is because the contact pressure in the seal seating has been optimized. Thanks to its robust, careful design, the TK has proven itself on the market over the course of decades.

Face to face dimension
-
The mechanical stop features rubber suspension and can be adjusted steplessly. Already during pressure equalization, it causes the valve disc to loosen from the seat.
-
Thanks to a patented self-pressing process, the seal on the seat only generates as much initial pressure as is necessary for a drop-tight shut-off.
-
The secondary shaft seals on both sides can easily be replaced, without requiring service interruption or further dismantling.
