Medical applications targeted with new aseptic spray valve

12 June 2009

EFD has introduced the 784S-SS aseptic spray valve for dispensing precise, consistent amounts of stent coatings, saline solutions, silicone oils and many other fluids used in medical and pharmaceutical production processes. According to a recent report, the medical coatings market is expected to exceed $5 billion by 2010, making controlled, efficient application of these materials more important than ever.

The new 784S-SS valve is precision machined from 316L stainless steel for excellent compatibility with a wide range of low- to medium-viscosity fluids. In addition, it features a unique aseptic design with a fluid flow path that is free of any entrapment areas - a critical consideration in sterile and aseptic fluid applications. The product incorporates EFD’s proven Low Volume Low Pressure (LVLP) precision spray technology, which reduces production costs through fast, controlled fluid application without waste or overspray. Instead of a standard spray nozzle, fluid is routed through a ¼” long disposable dispensing tip with a small (0.013”- 0.004”) internal diameter.

Depending on tip diameter, fluid viscosity and distance between the substrate and tip, the valve is capable of producing accurate, consistent spray patterns between 0.2 and 1.6 inches wide. Benefits in precision coating processes include greater process control, faster throughput, fewer rejects and lower production costs.
