There are 2 Liquidyn series based on the material viscosity; which are Liquidyn P-Jet Series Jetting Valves and Liquidyn P-Dot Series Jetting Valves

The pneumatically actuated Liquidyn® P-Dot jet valve provides very precise, repeatable jetting in the form of dots, beads, and lines, Designed for thicker medium-viscosity to highly viscous materials. With extremely short triggering intervals of less than 1 ms, it is possible to accurately apply small amounts of viscous fluids. Deposit volumes range from 3 nL to 200 nL and can be dispensed at frequencies up to 150Hz.

The Liquidyn P-Dot features interchangeable dispensing nozzles, tappets, and fluid inlet fittings, which make it easy to adapt for exacting application requirements. Wetted parts separate from the actuator simplify service and maintenance.

Dispense low- to medium-viscosity fluids in extremely accurate, repeatable beads and lines with the high-performance Liquidyn® P-Jet jet valve. Micro-deposits as small as 3 nL can be applied at up to 280Hz.

The Liquidyn P-Jet features easily exchangeable dispensing nozzles, tappets, and fluid inlet fittings, making it possible to customize for specific application requirements. Wetted parts separate from the actuator allow for fast, easy serviceability and maintenance.

Electro-pneumatically operated by a low voltage trigger, the Liquidyn P-Jet features an adjustable pulse signal. Valve open time can start at 2 ms. The dispensing tappet remains open until the trigger signal ends.

The valve was designed to dispense in industrial environments and features a low cost of ownership. Even the most demanding or delicate processes – whether due to product complexity or positional tolerances – are easy to implement with the Liquidyn P-Jet.
