Introduction
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.
Valve Speed and Deposit Size
The valve can produce micro-deposits ranging in size from 0.3–5.0mm
at dispensing frequencies of up to 150Hz, for a faster production
process. The distance between the valve and the substrate is usually
between 2 and 10 mm.
Modular, Exchangeable Components
Because the material-carrying components are separate from the
actuator, dispensing nozzles can be quickly and easily exchanged. The
exchangeable design makes material-type change-out and component
replacement fast and easy.
The Liquidyn P-Dot valve is configurable. Several choices for the
material supply components and sealing options are available, and an
optional nozzle heater can be installed to warm material at the nozzle.
How the Valve Operates
The Liquidyn P-Dot valve is electro-pneumatically operated by a low
voltage, 2 ms pulse signal. The dispensing tappet remains open until
the trigger signal ends. The valve is normally closed (NC) when idle,
thus reducing the possibility of unintended fluid release upon power off.
How the Valve is Controlled
The valve can be operated using a Nordson EFD Liquidyn controller
or directly by the customer via a 24V input using a customer-supplied
controller or a programmable logic controller (PLC).

Install a Nozzle Heater (Optional)
Install the optional nozzle heater as shown in the illustration below. A nozzle heater controls the temperature of
the material in the nozzle. The nozzle is secured minimally by the nozzle heater with an elastomer (heater O-ring)
between it and the valve. The nozzle is fully secured by the retaining nut.
You will need the following items:
• Nozzle
• Nozzle heater
• Nozzle heater O-ring (NBR or EPDM)
• Retaining nut
• Heater key
• Heater cable
Refer to “Nozzle Heaters” on page42 for component part numbers.
NOTES:
• The nozzle retaining nut predominantly secures and seals the nozzle in place. The heater remains in contact with
the retaining nut through pressure supplied by a heater O-ring, which creates a partial space between the heater
and the fluid body. This ensures thermal contact and allows the heater to rotate slightly even when the retaining
nut is fully tightened.
• The image below is based on a Liquidyn P-Dot valve with a standard nozzle heater. The mounting process is the
same for all valves.
NOTES:
• The electrical connection for the
heater is supplied through the
provided heater cable.

Connect Cables
Connect the M8 valve cable and other communication cables as applicable for your system to control the operation
of the valve. The diagram below shows some typical system control setups.
NOTE: The valve is triggered by a square-wave signal (24 VDC). Because the pulse time is set to 2 ms, the opening
time of the valve switches below 1 ms and automatically closes after each trigger signal. Most PLC systems make
use of high performance transistor outputs which are suitable to control the valve directly. The valve is electrically
connected to the control system via the supplied M8 valve cable.

Liquidyn P-Dot Series Jet Valves
Connect the Air Supply
To achieve consistent dispensing results, the process parameters must be kept constant. The valve has two air
pressure connections (operating pressure and fluid pressure) which must be continuously supplied with air pressure.
The level of pressure depends on the respective process. Each valve must be separately connected to a continuous
air supply adjustable through a precision pressure regulator. To keep the operating pressure stable and constant,
use a pneumatic accumulator (at least 0.4 liter volume).
For an air supply connection diagram, refer to “Installation Example” on page21.
CAUTION
Ensure that the pressure limit values for the syringe barrel and air pressure tubing are not exceeded.
1. For the operating pressure, connect 6 mm OD tubing to the plug-in connector on the side of the valve.
2. For the fluid pressure, connect 4 mm or 6 mm tubing to the syringe barrel adapter (syringe barrel installations
only).
NOTE: Nordson EFD recommends installing a precision pressure regulator with a maximum control tolerance of
0.2% and a pressure limit of 0–8 bar (0–116 psi).
