High preicsion Dispensing valve for glue liquid   The precision precision needle valve dispenses very precise micro-deposits down to fractions of a microliter. Pneumatically operated and adjustable, it delivers superior fluid dispensing control.Ideal for automated assembly processes, the valve’s adjustable needle stroke with a unique calibration feature provides the ability to maintain exact deposit size when dispensing fluid.The stainless steel shutoff needle seats in the hub of the dispensing tip rather than the valve body. Having fluid cutoff occur as close as possible to the dispensing orifice minimizes dead fluid volume.  Sales Points/Focus    Features·         Zero dead fluid volume·         Easy calibration, short setup time·         Consistent microdots as small as 0.18 mm (0.007”) diameter·         Unaffected by entrapped air in fluids·         Drip-free shutoff·         Compact and lightweight, space-saving installation·         Replaceable seals The air cylinder and material…
