ARTICLES NO LONGER AVAILABLE! The diaphragm metering valve VD-510-UV is ideally suited for liquids in the lower and medium viscosity range, whereby the diaphragm separates the wetted parts from the control unit. These are optimal operating conditions for the dispensing of cyanoacrylates, UV adhesives, inks, inks, electrolytes, glue, alcohols and other low-viscosity substances. Functionality:The valve is opened by a compressed air impulse. A built-in spring closes the valve. The VD-510-UV valve clearly proves its superiority, especially with high-frequency output cycles of small dispensing quantities. The respective quantities can be precisely adjusted via a fine adjustment at the head of the valve. The Luer Lock connector has a very small dead volume !
