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.
