3.2 Function
The valve features the VATLOCK sealing technology.
This means, the valve is mechanically locked in the closed position. In the open position,
the mechanism is not locked.
Leaf springs hold gate and counter-plate against the carriage with the ball retainers. The
ball pairs are in the detents.
For closing, the mechanism is moved forward into the closing position. The locking starts
after the leaf spring stop touches the body. The ball retainers move the ball pairs out of the
detents. Gate and counter-plate are spread apart. The gate seal is pressed against the
sealing surface without scuffing.
The arrangement of the ball pairs ensures an increase of the sealing force with vacuum on
either side of the gate.
During opening the movements proceed in the reverse order. See «Figure 3-3».

1. Remove protective covers from body flanges.
2. Clean sealing surfaces and seals of both flanges;
see (1) and (2) according to «Figure 4-1» on page 13 .
The valve seat side is marked with the symbol «
∇
» on flange «A».
3. Lift valve to the mounting position.
4. Mount four screws (3) according to «Figure 4-1» evenly in crosswise order until the seal
touches the sealing surface.
5. Tighten all screws with the torques appropriate for their property classes.
4.2.1 Admissible forces and bending moments
Forces from evacuating the system, from the weight of other components or
from baking can lead to deformation of the valve body and to malfunction of
the valve. The stress has to be relieved by suitable means, e.g. bellows
sections.
The following forces or moments are admissible:
DN (nom. I. D.) Axial tensile or com-
pressive force «FA» Bending moment «M»
