2. TA-Luft certified safety
Adjustable stem sealing, located below the top flange, allowing adjustment without removing the actuator.
3. Long service life
The insert ring, mounted with its orientation against the direction of flow, actively protects the integrated laminated seat/seal from premature erosion and wear, providing longer service life and reduced costs and downtime.
4. Insert Ring
Pressure-sealed bolted design - located outside of the flange sealing surface according to TA-Luft.
5. Triple offset valves
Due to the design of the seat, triple offset valves are torque-seated. Therefore the actuator torque is constantly used to ensure contact pressure between the seating surfaces. This is necessary to provide zero leakage performance.
6. Multiple mounting standards
face-to-face dimension acc. to EN 558 T1, line 20 (25/16) DIN 3230 / K1 (K2/K3)
8. Precise mounting
Simple and precise mounting using wafer body location holes for all face to face dimensions.
