Micro-dispensing Valve P-Dot
Pneumatically operated High-speed Valve for none-contact jet dispensing of media with high viscosity.
The Micro-dispensing Valve P-Dot is designed for none-contact dispensing of adhesives, silicones, lacquers, oils and greases. Because of its extreme short triggering time (<= 1ms), it allows the application of smallest quantities of high viscosity media at distances ranging from 2 to 40 mm with pin point precision. The amount of fluid, possible to be dispensed, can be varied between 10 and 200 nl per triggering. Depending on the medium, dot sizes of a minimum of 350 nm up to 2000 nm can be realized.
Features, Micro-dispensing Valve P-Dot:
- Switiching time ≤ 1 ms
- Driven by 24 V DC input signal
- Normally closed
- Volume per shot (10 – 200 nl)
- High accuracy < 1%
- Robust and suitable for industrial applications
- Easy handling and maintainance
