6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform personnel about the technical data.
6.1
Technical data
Unique Mixproof LP-F is remote-controlled by means of compressed air.
The valve is a normally closed (NC) valve. It is as standard supplied seat lift, which enables handling of two different products
at the same time, or safe handling of one product while seat-lift cleaning operations are being conducted in the other portion
of the valve – all without any risk of cross-contamination.
The 6” valve is as standard also equipped with balanced lower plug to protect against the effects of high pressure and water
hammer.
The 4” valve is, in order to accommodate 45mm particles, not supplied with balanced lower plug.
