SMP-BCA aseptic mixproof valve
The SMP-BCA aseptic mixproof valve is a normally closed (NC) valve with a proven PTFE/EPDM diaphragm. The special designed aseptic diaphragm hermetically seals against intrusion from the atmosphere and ensures full protection against the effects of microorganisms. It also prevents product build-up on the product contact surface.

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.

Two small pneumatic normally open (NO) valves enable a sterile barrier to be established in the leakage chamber through the continuous application of steam. The chamber must be clean and sterile when the main valve is closed.

For changeover valves, a single seal plug separates the lower product lines but does not require the use of a sterile barrier in the leakage chamber.

SMP
Ideal for handling sanitary process flows through matrix piping systems, SMP mixproof valves are standardized, cost-effective alternatives to Unique mixproof valves.

Economic mixproof valves
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.

High application flexibility
Based on a modular structure, SMP mixproof valves have several valve 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.

Plus SMP mixproof valves are constructed from a series of base components, which enables valves 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.

SMP mixproof valve range
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
  • For more information, please refer to Documentation.

Aseptic version
The aseptic version of Alfa Laval's SMP mixproof valve is called SMP-BCA, which is designed for use under mixproof aseptic conditions and sterilization 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.

Compliance with most hygienic standards
Alfa Laval SMP valves meet most standards requested in the dairy, food and beverage, and personal care industries.

Testimonial from Chemical Engineer

"Thanks again for reacting so quickly and meeting me halfway with the element. We will be able to get installed and have things keep moving overnight with the night crew. The little things like this are always greatly appreciated when working with Liquidyne."

Testimonial from VP Antibody Manufacturing

“This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
