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 dispensing valves 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.
