WK 44 Sanitary Ball Valve
Brand: Worcester-ControlsSeries WK 44 Clean Valves are operating dependably in processes in the pharmaceutical, biotech, food, cosmetic, paint, chemical and other industries where microbes, media deposits, particle generation 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 help assure quality production with minimum downtime. They last many times longer than diaphragm valves and prevent catastrophic failure.
