Sterile Barrier

The Pure-Flo Sterile Barrier design addresses the issues of achieving sterile barrier technology, utilizing a small dimensional envelope while minimizing contact surfaces and hold up volume.

The Integral Sterile Barrier assembly consists of four valves machined from a single block of stainless steel. The common chamber is located in the center of the assembly and the independent ports are located on the ends of the assembly. The assemblies consist of two product valves, a steam injection valve and a condensate drain valve. When the two product valves are open and the steam injection and condensate valves are closed, product flows through to the reactor. When the product valves are closed, a chamber is formed between the two divert valves which, when injected with steam, provides a sterile barrier isolating the reactor.
