P-Dot CT Pneumatic Jet Valve High-precision micro-dispensing: reliable, fast and user-friendly The P-Dot CT is a high performance jet valve designed for the non-contact micro-dispensing of medium- to highviscosity 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 from 0.3 to 5 mm. The distance between the valve and the substrate is usually between 2 and 10 mm. The P-Dot CT valve’s fluid-carrying components are 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 Nordson EFD 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 P-Dot CT valve non-contact dispensing. The high-performance P-Dot CT valve provides both non-contact and contact dispensing capability. Features • 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). • Modular design. • 3D dispensing. Benefits • High repeatability and high accuracy provide very consistent dispensing results for higher productivity. • Interchangeable components mean quick changeout of fluid types and easy service and maintenance. High repeatability and high accuracy provide very consistent dispensing results.

Flexible Mounting Options Specifications Item Maximum fluid pressure Fluid inlet thread Maximum operating frequency Pulse time Input voltage Power consumption Maximum valve heating temperature 90° C (194° F) The P-Dot CT valve provides three-dimensional (3D) dispensing for jetting into difficult-to-access areas and onto uneven or unusual surfaces. This mounting flexibility, along with a small footprint, makes it ideal for installation into tight spaces. Valve Control The valve can be operated using a Nordson EFD valve controller or directly by the customer via a 24V input (for example, from...
