Launched recently by Intertronics are two new dispensing valves especially suitable for cyanoacrylate adhesives as well as other volatile and/or low viscosity materials such as UV cure adhesives, solvents, varnishes, lacquers or inks.
The IDM HDV-130 and IDM HDV-120 Handheld Diaphragm Dispensing Valves offer a lightweight handheld “pencil grip” design which facilitates manual dispensing applications. They are an alternative to “pinch-tube” style dispensing pens and valves, providing improved accuracy, usability, and reliability.
Both the HDV-130 and the HDV-120 utilise proven diaphragm technology to control material flow. They may be fed from pressure pots, cartridges, syringes or even with a gravity feed. The HDV-130 is pneumatically actuated, typically from a dispensing controller like the Fisnar SL101N which allows timed shots. The HDV-120 is actuated via a lever for simple manual control.
The all plastic construction of wetted parts, including a patented silicone/PTFE diaphragm disk, means these valves are compatible with fluids such as cyanoacrylate and anaerobic adhesives, conformal coatings, solvents, oils and many other low-to-medium viscosity liquids. A stroke adjustment provides fine tune control of the fluid flow rate, and both valves accept industry standard Luer lock dispensing needles and tips.
