SMP Valve
Alfa Laval SMP Double Seal Valve
Ideal for sanitary process flows through matrix piping systems, Alfa Laval SMP-BC and SMP-BCA Mixproof Valves are standardised, cost-effective solutions that safely handle the simultaneous flow of two different products.
Standardised and cost-effective, the top-loaded Valve is designed for quick leakage detection to maximise product safety and low maintenance due to few moving parts. It is often used in Cleaning-in-Place (CIP) lines and can also be used in other systems handling products.

SMP Valve Key Features
Alfa Laval offers two Double-Seal Mixproof Valves: The Alfa Laval SMP-BC and the aseptic version, SMP-BCA. The SMP Valves enable the flow of two different media through the same Valve simultaneously without any risk of cross-contamination. This increases operating efficiencies and significantly reduces operating costs.
The Alfa Laval SMP Mixproof Valve range offers two standard cost-effective alternatives to the premium Alfa Laval Unique Mixproof Valve range:
- SMP-BC Mixproof Valve for applications that require additional safety, leak detection and CIP
- SMP-BCA Mixproof Valve for aseptic applications
The SMP-BC Mixproof Valve is fitted with two small pneumatic normally open (NO) Valves, a detecting Valve and a CIP-Valve.
The Valve plug has two seals, which form an atmospheric leakage chamber. Any product leakage is discharged through the detecting Valve. The leakage chamber may be cleaned by supplying CIP into the detecting Valve. The SMP-BC is insensitive to water hammer in the product line above the plug.
For changeover Valves, a single seal plug separates the lower product lines.
SMP-BC
SMP-BCA
The aseptic version of the SMP Mixproof Valve is the SMP-BCA, which is designed for use under Mixproof aseptic conditions and sterilisation involving high temperatures.
The straight forward design keeps liquids separate by using two seals on the same plug, with a leakage chamber in between.
The PTFE / rubber diaphragm following the movement of the plug in the upper section of the Valve body ensures that there is no increase in the concentration of microorganisms in the product during processing.
High Application Flexibility
Based on a modular structure, SMP Mixproof Valves have several bodies and components that can be combined in various ways. These self-draining Mixproof Valves can, for instance, be configured as stop Valves and changeover Valves. SMP Mixproof Valves are constructed from a series of base components, which enables them to easily be configured to meet different requirements in sanitary and aseptic applications.
Simplified Valve Maintenance
Few moving parts, a top-loaded plug, a maintenance-friendly actuator make SMP Mixproof Valves easy to disassemble for quick, straightforward maintenance.
Compliance With Most Hygienic Standards
Alfa Laval SMP Valves meet most standards requested in the dairy, food and beverage, and personal care industries.
How the SMP Valve Works
The Alfa Laval SMP Mixproof Valves are controlled from a remote location by means of compressed air. The SMP-BC and SMP-BCA Mixproof Valves have different operating principles.
