Alfa Laval SMP-BC Mixproof Valve
Concept
SMP-BC is a 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 systems
not experiencing 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 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. Leaking product 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.

Standard design
SMP-BC is available in two versions, as a shut-off valve with one
valve body or as a change-over valve with three valve bodies (sizes
DN125-150 only as shut-off valve).
The valve bodies and the external actuator are clamped together.
SMP-BC is fitted with one detecting valve and one CIP-valve. The
seals and the lip seal can be serviced after removing the actuator.
Options
A. Male parts or clamp liners in accordance with required standard.
B. Control and Indication: IndiTop, ThinkTop or ThinkTop Basic.
C. Actuator with stronger spring.
D. Larger actuator for valve sizes 38-51 mm/DN40-50.
E. Larger actuator for valve sizes 1½”-2”.
F. CIP installation kits.
G. Other valve body combinations.
H. Surface roughness, product wetted parts: Ra ≤0.8 μm.
I. Surface roughness, product wetted parts: Ra ≤32 μin.
J. Product wetted seals of NBR or FPM.
K. Service tools for actuator.
L. Tool for plug seals (Necessary for changing the seals).
SMP-BC is available in two versions, as a shut-off valve with one valve
body or as a change-over valve with three valve bodies (sizes 5” +
6” only as shut-off valve).
The valve bodies and the external actuator are clamped together.
SMP-BC is fitted with one detecting valve and one CIP-valve. The
seals and the lip seal can be serviced after removing the actuator.
Note!
For further details, see also instruction IM 70771.
It is recommended, due to the valve size and weight, to use supporting
equipment, handling and installing the valve. Guidelines are given in
the instruction manual (IM70771). Alfa Laval is not able to supply the
recommended supporting equipment.

Caution, opening/closing time:
Opening/closing time will be affected by the following:
- The air supply (air pressure).
- The length and dimensions of the air hoses.
- Number of valves connected to the same air hose.
- Use of single solenoid valve for serial connected air
actuator functions.
- Product pressure.
