Close-coupled valves aimed for biotech uses
15 Jan 2000
A new range of solid configuration `close-coupled' branch valves is designed specifically to meet the needs of the biotechnology and pharmaceutical industries, says its maker, Alfa Laval Saunders.
The design ensures that `deadleg' areas are kept to a minimum, which improves the integrity of the process and reduces the risk of contamination from stagnant material trapped in the valve body. The valves are machined from solid barstock, the company says, which eliminates the need for fabrication welding.
The valves are used extensively as sampling and injection points on sterile process lines and water systems; basically, for any application where the main process line is larger than the valve size. The units are available in 1/2in-4in sizes, and are compatible with Saunders' actualtion packages and FDA-conforming diaphragms.
