Combination Style:



sanitary pneumatic seat valve,designed for safety and leak detection when two different products
flow through only one valve.The valve is often used as a part in CIP return lines or other systerms not experiancing
pressure spikes offering leakage detection for greater safety.

Working Principle:
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(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.Leaking products flows into the leakage chamber and is discharged through the detecting
valve.SMP-BC can be cleaned by CIP by supplying compressed air to the actuator(see fig 1).During cleaning of
the valve,flow pattern against the closing direction of the valve plug makes SMP-BC insensitive to water hammer.
