Standard: drive unit right sided            Special: drive unit left sided

With asymmetric components the actuation is positioned on the right side as standard
according to the illustration. If for space reasons the actuator has to be positioned on the opposite side – left-hand side installation – it has to be noted explicitly. No extra charge.

 

 


 

 

 

From a diameter of 150 mm all two-way-valves are available with an inspection hole of
115 mm diameter to control the inside valve.
