Hot melt jet valves at NEPCON South China

An internal spring return makes the valves fully adaptable for use with Techcon Systems controllers. A short opening stroke provides an extremely fast and positive shut-off. The seal-less valve design offers excellent moisture sensitive resistance and the incorporated diaphragm creates a barrier between the wetted parts and the air cylinder.

The TS9200D Jet Tech is a non-contact dispense valve capable of jetting fluid viscosities to 400,000 Cps. Jet Tech offers a fast jetting action producing hundreds of precise droplets in less than one second. The main feature of the valve is a single, easily replaceable diaphragm to eliminate dynamic fluid seals found in other jet valves. No longer is it necessary to disassemble, clean and replace worn seals, which translates into saving time and money. The diaphragm also allows fast cycle rates because of its very small mass. There is no large sliding valve stem that slows down the process. With this novel diaphragm design, the energy needed to eject a drop can be adjusted providing a wider process window.
