Liquidyn P-Dot CT Actuator

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.
