Why Choose the TD908CS-30
The TD908CS-30 replaces inconsistent pneumatic dispensing with a precision servo-driven screw, giving you micro-volume repeatability down to ±0.001 ml. Its modular tungsten-carbide screw assembly is quick to replace and built for long production runs, while the patented valve structure keeps maintenance consumables to a minimum. With SUS304/PTFE wetted parts and temperature capability up to 200 °C on the valve body, it handles PUR and PUH hot-melt fluids reliably across automotive, electronics, medical and optical applications.
