This valve is suitable for use in pharma-grade water systems
The DV-ST Ultra-Pure Valve (photo) is designed to meet the demands of pharmaceutical-grade, purified-water systems. This compact, lightweight diaphragm valve is modular in design, which enables its use in a diverse array of purpose-built configurations, to control and maintain water quality, flow and temperature in the distribution loop during pharmaceutical manufacturing. This valve has low specified sulfur content (which enables superior weld quality), and its stainless-steel valve body has low delta-ferrite content, says the company. It also has a relatively low weight, which reduces the stress on the piping. — Alfa Laval Kolding A/S, Kolding, Denmark
