Techcon Systems, distributed in Italy by E.O.I. Tecne, presents the TS9300HM Hot melt jet valve series, easy to clean and with easily replaceable single diaphragm which eliminates dynamic fluid seals common in other jet valves. The valve includes a disposable feed tube so only the nozzle plate and diaphragm are in contact with the fluid, and the isolated jetting mechanism ensures fluids are contamination-free.
The patent pending diaphragm design enables to exchange syringes quickly, requiring minimal cleaning, and the TS9300HM has a thermal jacket surrounding the high-temperature feed tube, so the syringe can easily be removed with the feed tube attached, not requiring to clean residual PUR between the syringe and the jet. Dual temperature controllers, for the jet and the heater, allow the nozzle to be heated to optimum jetting temperatures, up to 150°C, while keeping the PUR fluids at reduced temperatures and the jet actuator below 55°C. The Techcon’s stand-alone TS930 Controller is also available to help program the TS9300HM Hot melt jet valve, with dual independent temperature controllers and dual independent power supplies for the jet and the heater, along with precision air regulators and gauges to fine-tune the jetting parameters.
