High-precision micro-dispensing: reliable, fast and user-friendly
The Liquidyn®P-Dot is a high performance jet valve designed for the non-contact micro-dispensing of medium- to high-viscosity ﬂuids, including oils, greases,adhesives, silicones, lacquers, ﬂuxes, and medical and chemical substances. Depending on the material, the valve can dispense dot diameters ranging in size from0.3 to 5 mm. The distance between the valve and the substrate is usually between 2 and 10 mm.
The Liquidyn P-Dot valve’s ﬂuid-carrying componentsare separate from the actuator, allowing them to be quickly and easily exchanged. This modular design makes ﬂuid-type changeout and component replacement fast and easy.
Electro-pneumatically operated by a low voltage pulse signal, the valve can be operated using either a Liquidyn valve controller or a customer-supplied high-level controller, such as a PLC. The valve switches below 1 ms and automatically closes after each trigger signal. The valve is closed when idle (NC: normally closed).
Even the most demanding or delicate processes— whether due to product complexity or positional tolerances — are easy to implement with Liquidyn P-Dot valve non-contact dispensing.
•Suitable for highly viscous ﬂuids
•Dispensing volume starting at 3 nL
•Dispensing frequencies as high as 150Hz
•Bead or line dispensing capability
•Low voltage operation (24 VDC)
•High repeatability and high accuracy provide veryconsistent dispensing results for higher productivity.
•Interchangeable components mean quick changeoutof ﬂuid types and easy service and maintenance.
•IP65-compliant construction makes the valve dust-proof and wash-down friendly.
