Technical Data
9.4.
Opening and closing times
The actuating times depend on the length of the air line between
the magnet valve to the air control and the actuator.
For air lines with a length of up to 1 m, the opening time for
butterfly valves DN 25/1" to DN 100/4" at 6 bar control air pressure
amounts to about 1 second. The closing time, after air shut-off,
depends on the nominal dimension and amounts to 2 to 3
seconds.
If the valves are subject to strong friction, e.g. through dry seals,
the actuating times extend accordingly.
