A Clean Valve to write your specs around: Tube bore, metallurgy, surface finish, shut-off, cleanability and automation

Series WK 74 clean valves operate dependably in the pharmaceutical, biotech, food, cosmetic, paint, chemical and semi-conductor manufacturing industries where microbes, media deposits, mineral impurities and cross-contamination can threaten the quality of the product. The high-purity design, high vacuum rating, high cycle life and pressure/temperature rating of these valves make them ideal for applications from sterile steam to nutrient inlets to high-purity water. The performance of the WK 74 Tube Bore Clean Valve is based on a combination of high standard specifications.

Features

• Tube Bore* The inside diameter of WK 74 valve components are tube bore dimensions so that the valve precisely matches the tubing it is welded to. This prevents buildup of pyrogens or bacteria.
• Low Ferrite Content WK 74 valves are made of 316L stainless steel with a guaranteed ferrite content of less than 5%. This prevents rouging resulting from minerals and impurities drawn from higher fer
• High Integrity Welds The tube ends have a verifiable sulfur content between .005% and .016%. With a low sulfur content, comparable to that of the process tubing, the quality of the weld is assured.
