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
SMP-BC is remote-controlled by means of compressed air. The valve is a normally closed (NC) valve.
The valve is fitted with two small pneumatic normally open (NO) valves, a detecting valve and a CIP-valve. The valve plug (the
upper plug in a change-over valve) has two seals, forming a leakage chamber under atmospheric pressure between them.
