Acetal copolymer fluid body and UHMW diaphragm. Includes fluid inlet fittings #7021499 and #7007038. Features and Benefits • High-flow capability for thicker UV-cure coatings • Valve open time as short as 15 milliseconds • Positive shutoff, no seals • Compact and lightweight The 752HF valve system is specifically designed for precise dispensing of UV-cure resins and similar fluids used in media manufacturing of Blu-Ray DVDs, DVDs, and CDs. Unrestricted material flow reduces turbulence and the formation of micro bubbles.
