Long service life and tightness, compared e.g.
with ball valves (typically with floated bearing)
which can wear out the seal with each stroke.
Very simple maintenance: The valve body can
remain installed in the pipeline during valve
maintenance. The actuator including the plug
can be easily unscrewed.
The simple maintenance also allows economic
and space-saving welding constructions that
prevent leakage at the connections.
For every component of the valve there is a spare
part available.
The most compact valve solution on the market.
Flexibility in the supply air connection by actuators
that can rotate by 360o.
Valve position indication possible, even in the
"normally open" versions.
