6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform all personnel about the technical data.
6.1
Technical data
principle The valve is a pneumatic seat valve in a hygienic and modular design 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 SSV Two Step valve comes in a one or two body configuration. With its module built structure it is
designed for flexibility and easy customization through the electronic configurator.
