TZ01
The TZ01 is our double eccentric butterfly valve. The specially developed dynamic seal is self-pressing and adapts to system pressure. Only as much system pressure is generated from the seal on the seat as is necessary for the drip-tight seal, due to the respective operating pressure at the time. This results in a minimal amount of torque required for actuation. The special shape of the seal means the direction of pressure can come from both sides.

-
Due to the special shape of the seal, the pressure direction is possible from both sides.
-
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.
