DMP diaphragm valve dispenses with frequent cleaning

Techcon Systems has developed a Disposable Material Path (DMP) diaphragm valve. The TS5624DMP valve features a ‘first to market’ disposable material path, enabling difficult fluids and pre-mixed two-part epoxies to be dispensed without the need for frequent cleaning. The entire wetted area can simply be replaced in a matter of seconds, while the valve stays on the production line.

The wetted parts are manufactured from black Polyethylene to prevent moisture and UV light from coming into contact with the dispense fluids. As a result, moisture sensitive fluids such as Cyanoacrylate and UV cured adhesives can be dispensed reliably and accurately.

TS5624 dispenses low to medium viscosity fluids over a wide range of shot and bead sizes, down to a fraction of a μl. 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 valve comes standard with a mounting bracket kit, valve air hose, luer lock fluid line, sample packet of DMP inserts and a dispensing tip selection pack. Typical applications include dispensing pre-mixed two-part epoxies and cyanoacrylate in bonding applications, and applying UV lacquer in CD/DVD spin coating applications.
