Automations-System GEFA-MULTITOP

• Standardized mounting flange acc. to DIN 3337/ISO5211
• Direct mounting of actuator, allowing correct alignment
• Variable topworks arrangements, allowing for different actuator sizes to be mounted

Adjustable stem sealing, located below the top flange, allowing adjustment without removing the actuator.

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.

Pressure-sealed bolted design - located outside of the flange sealing surface according to TA-Luft.

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.

face-to-face dimension acc. to EN 558 T1, line 20 (25/16) DIN 3230 / K1 (K2/K3)

• Stem bearings absorb adverse loads and securely support the stem
• Continuous secured stem guidance provides maximum support for the single-piece shaft constructed of high-tensile materials

Simple and precise mounting using wafer body location holes for all face to face dimensions.
