6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform the personnel about the technical data.
6.1 Technical data
The valve is a pneumatic seat valve in a hygienic and modular design for a wide field of duties, e.g. as a shut-off valve with
two (2) or three (3) ports or as a change-over valve with three (3) to five (5) ports. The valve is remote-controlled by means of
compressed air. It has few and simple moveable parts which results in a very reliable valve and low maintenance cost.
