Introduction To SMP-BCA

The Alfa Laval SMP-BCA Mixproof Valve with PTFE Diaphragm stands as an aseptic double-seal valve crafted for use under aseptic conditions and sterilization at elevated temperatures. Derived from the Alfa Laval SMP-BC, the SMP-BCA showcases a straightforward design that maintains liquid separation through two seals on the same plug, with a leakage chamber in between. Featuring a PTFE face and reinforced EPDM rubber backing, the diaphragm mirrors the plug movement of the upper valve body, ensuring no increase in the concentration of microorganisms in the product during processing.

SMP BCA How It Work

The Alfa Laval SMP BCA Mixproof Valve is operated by means of compressed air from a remote location. This aseptic valve is a normally closed (NC) valve. A specially designed diaphragm unit with a PTFE face and reinforced EPDM rubber backing ensures sterile steam sealing prevents intrusion from the atmosphere and does not allow product residues to build up on the product contact surface. The product lines are separated by two seals and a sterile barrier chamber to prevent mixing the products and to ensure immediate indication in the event of leakage from one of the seals. Two small pneumatic normally open (NO) valves control flow to and from the sterile barrier chamber. The barrier chamber must be clean and sterile when the main valve is closed.
