6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform the personnel about the technical data.
NO = Normally open. NC = Normally closed.

Technical data
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.
Standard Design The Unique Single Seat DN125 and DN150 Valves come in a one or two body configuration. The actuator
is connected to the valve body by means of clamp rings.
