Introduction
The Liquidyn P-Jet SolderPlus pneumatic micro-dispensing jet valve
system is designed for the non-contact dispensing of EFD SolderPlus
solder paste. Nordson EFD solder paste is pre-qualied for use with
the SolderPlus valve, making it an ideal choice for a complete jet
dispensing system for solder.
Valve Speed and Deposit Size
Depending on the type of solder paste, the valve can produce microdeposits as small as 700 μm in diameter.
Modular, Exchangeable Components
Because the material-carrying components are separate from the
actuator, dispensing tappets and nozzles can be quickly and easily
exchanged, allowing the valve to efciently dispense highly abrasive
mediums as well. The exchangeable design also makes material-type
changeout and component replacement fast and easy.
The Liquidyn P-Jet SolderPlus valve is congurable. Many choices for
the material supply components and the nozzle are available, including
an optional nozzle heater.

valve with a syringe barrel material supply
How the Valve Operates
The Liquidyn P-Jet SolderPlus valve is electro-pneumatically operated
by a low voltage, adjustable pulse signal that can start at 2 ms. The
dispensing tappet remains open until the trigger signal ends. The valve
is normally closed (NC) when idle, thus reducing the possibility of
unintended uid release upon power off.
How the Valve is Controlled
The valve can be operated using a Nordson EFD Liquidyn valve
controller or directly by the customer via a 24V input using a customersupplied controller or a programmable logic controller (PLC).
The Liquidyn V200 controller can be used
to control the operation of the Liquidyn
P-Jet SolderPlus valve

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 “Replacement Parts” on page35 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 uid 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-Jet valve with a standard nozzle heater. The mounting process is the
same for all valves.

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). The length of the pulse from the control signal
denes the opening time of the valve and can be set from 2 ms to innity. 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.

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 uid 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).
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 uid pressure, connect 4 mm or 6 mm tubing to the syringe barrel adapter.
NOTE: Nordson EFD recommends installing a precision pressure regulator with a maximum control tolerance of
0.2%.

deposit size. The following conditions apply to Pulse Time:
1.0 bar (14.5 psi)
starting value
6 bar (87 psi) starting
value
Do not adjust
open
• The pneumatically actuated dispensing nozzle remains
open as long as it is triggered.
• The dispensing volume is affected by the adjustment of
the triggering pulse.
• The minimum Pulse Time is 2 ms. The valve cannot
operate correctly at Pulse Times below 2ms.
Frequency
Frequency is the number of tappet movements per second. A dispensing cycle consists of the Pulse Time and the
pause time.
Physical Quantity Formula Unit
Frequency (f) f = 1 / T 1Hz (hertz) = 1 / s
Dispensing cycle T = 1 / f 1 s (second) = 1 / Hz
1 ms = 0.001 s (second)
Higher-level controllers may not allow you to enter the exact frequency. If such cases, frequency is set using the
length of the pulse and the pause time.

Fluid Pressure
The uid pressure must be properly set to ensure that material is supplied at a consistent volume. Consider the
following when setting the uid pressure:
• The uid pressure must stay within the tubing pressure specications.
• Fluid supply tubing must be resistant to chemicals.
• The uid pressure must be high enough for the material to exit the nozzle opening.
• The required uid pressure will vary depending on the material, its viscosity, and the ambient temperature.
• Decreasing the uid pressure too much may, in extreme cases, prevent proper deposit separation from the
nozzle.
• Prevent pressure uctuations. Note that pressure loss due to friction occurs as material ows through the
material delivery components.
Recommended Setup Adjustments
The following table provides recommended adjustments to help you quickly nd optimum system settings

Tappet Adjustment
The valve is equipped with two mechanisms for tappet
adjustment:
Stroke adjustment
knob
• Force screw (non-slip knurled screw) — sets the dynamic
of the tappet movement.
• Stroke adjustment knob (fine diamond knurl screw) —
sets the tappet stroke.
The factory settings for both mechanisms are appropriate for
most applications. However, depending on the dispensing
Force screw
task and on the material, each can be adjusted to ne-tune the
dispensing result.
CAUTION
When dispensing solder paste, do not adjust the tappet of a wetted and closed valve. Doing so can grind material
into the nozzle, causing nozzle clogging and other related problems. Refer to “Appendix C, Special Instructions for
Solder Paste Dispensing” on page46 for steps that apply only to solder paste dispensing.
Adjusting the Force Screw
Adjust the raster element (see NOTE below) and then turn the force screw clockwise (as seen from an aerial view)
to change the dynamic of the tappet movement. In most cases, simultaneously increasing the operating pressure is
helpful.
NOTE: Use the spring-loaded raster element as follows:
• Completely loosen the element to turn the force
screw.
• Half-tighten the element to hear a clicking sound
when you turn the force screw.
• Completely tighten the element to secure the force
screw.

Nozzle Heaters
Many materials can easily be dispensed without preheating. However, it is often advisable to preheat highly viscous
materials just before application to lower the viscosity. Doing so can prevent variations in viscosity. The use of
a nozzle heater guarantees a constant temperature of the material to be dispensed at the nozzle. Contact your
Nordson EFD application specialist for assistance.
A nozzle heater can be installed on the valve in place of the retaining nut. The heater can be controlled using a
separate temperature controller (such as the Liquidyn T10) or by the Liquidyn V200 controller.
NOTES:
• Nozzle heater O-rings are available in NBR or EPDM. Refer to “Nozzle Heater O-Rings” on page40 for part
numbers.
• A special heater key is required for installation. Refer to “Heater Key” below for the part number.
• A nozzle retaining nut suitable for either a standard or small nozzle heater is required. Refer to “Nozzle and Nozzle

Appendix A, About Non-Contact Dispensing
The way a micro-dispensing valve system works for the non-contact dispensing of micro-deposits of uid is
comparable to the way an ink-jet system works. In both systems, a jetted deposit with a spherical head and a thin
thread (shaped much like a tadpole) is formed. The dimensions vary depending on the material being dispensed, the
process, and the valve settings.
As the deposit is squeezed (or jetted) out of the nozzle opening, the thin thread constricts because of the absence
of further uid supply, the surface tension, and also the continual movement of the deposit, until the deposit nally
separates from the nozzle opening. The thread extending from the deposit’s spherical head is either absorbed by
the head or separated into at least one more (sometimes many more) smaller head. This depends on the rheological
properties of the uid. At low airows or in asymmetrical drop-off conditions, a smaller head can land on the
substrate next to the main head, creating satellite drops. The thin thread formed at the nozzle output retracts back
into the nozzle due to the surface tension and remains at the nozzle output. This residue at the nozzle output can
have a negative inuence on the dispensing properties of the valve.
The formation of satellite drops and / or nozzle contamination can be reduced or eliminated by using the correct
dispensing settings.
Low Viscosity Materials
Try the following to reduce or eliminate the formation of satellite drops: Reduce the pressure supplied to the material
by reducing both the uid pressure and the operating pressure and also by loosening the force screw. Refer to
“Adjusting the Force Screw” on page28.
NOTE: With low viscosity materials, nozzle contamination is usually a minor issue because the subsequent drop
removes the residue at the nozzle output.
High Viscosity Materials
With high viscosity materials, the thin thread that retracts back into the nozzle and the resulting nozzle
contamination can negatively affect the dispensing process. Try the following to reduce or eliminate nozzle
contamination:
• Increase the amount of supplied force. The amount of force depends on the operating pressure and the
pretension of the valve tappet. Increasing the amount of force can have a positive effect on the drop-off
properties of the deposit and thus improve process reliability. Refer to “Adjusting the Force Screw” on
page28.
• Warm the material being dispensed to reduce the viscosity. This is particularly effective for highly viscous
materials. In most cases, the dispensing process reliability of highly viscous materials improves with decreased
viscosity. Material warming can be accomplished by installing a nozzle heater. Refer to “Install a Nozzle Heater
(Optional)” on page20.
NOTE: In general, viscosity halves per 10 Kelvin temperature unit increase. Exceptions are silicone oils and greases,
although elevating the temperature of these materials can lead to improvement.
Deposit Size
The dispensed volume of a deposit depends on the following parameters:
• Cross section of the valve
• Operating pressure
• Fluid pressure
• Position of the stroke adjustment screw or the force screw.
The smallest possible deposit size is subject to physical limitations. The smaller the deposit, the higher the surface
tension in relation to its mass. Thus, the amount of required energy needed for the launch of a deposit raises
signicantly in relation to its mass. At a certain point, it is physically impossible to transfer the required energy to the
dispensed material any longer, particularly in the dispensing of highly viscous materials.

Liquidyn P-Jet SolderPlus Jet Valve
Appendix B, P-Jet SolderPlus Valve Interface Overview
The Liquidyn P-Jet SolderPlus pneumatic micro-dispensing jet valve system is designed for the non-contact
dispensing of EFD SolderPlus solder paste. The valve can be operated using a Nordson EFD Liquidyn valve
controller or directly by the customer via a 24V input using a customer-supplied controller or a programmable logic
controller (PLC).
Electrical Control
The valve is triggered by a square-wave signal (24 VDC). The length of the pulse from the control signal denes the
opening time of the valve and can be set from 2 ms to innity. 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.
NOTE: To continuously dispense the exact amount with every shot, the Pulse Time must be kept constant. Observe
the cycle time of the PLC; if necessary, check the signal with an oscilloscope.

Optional Nozzle Heater Control
A nozzle heater can be installed on the valve in place of the retaining nut. The heater can be controlled using a
separate temperature controller (such as the Liquidyn T10) or by the Liquidyn V200 controller.
To use another method for controlling the heater, the following information applies:
• The heater comprises a heating coil and a 100-ohm platinum (PT100) resistance temperature detector (RTD).
• The heater can be triggered by most control units.
• Heater power consumption is approximately 1.3 Amps, with 24 VDC used during the heating process.
NOTE: The maximum heater temperature is 90° C (194° F). For consistent dispensing results, keep the control
deviation to a minimum (lower than 3%).

Pneumatic Control
To achieve consistent dispensing results, the process parameters must be kept constant. The valve has two air
pressure connections (operating pressure and uid 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).
Operating Pressure Specification
For the operating pressure, connect 6 mm OD tubing to the plug-in connector on the side of the valve.
Item Specification
Input air pressure 3–8 bar (44–116 psi)
Fluid Pressure Specification
For the uid pressure, connect 4 mm or 6 mm tubing to the syringe barrel adapter (syringe barrel installations only)
Item Specification
Fluid pressure range 0.1–4.1 bar (1.5–60 psi)
Maximum uid pressure 100 bar (1450 psi)
CAUTION
Ensure that the pressure limit values for the syringe barrel and air pressure tubing are not exceeded.
NOTE: Nordson EFD recommends installing a precision pressure regulator with a maximum control tolerance of
0.2%.
Valve Configuration Options
• The uid body can be mounted in other 90-degree positions.
• The operating air pressure connector can be mounted on the opposite side of the valve.
• Standard cartridge centering is 10 cm2 (1.6"2); 30 cm2 (4.7"2) can be supplied upon request.
• The valve can be supplied without cartridge centering, in which case a tubing connector is mounted on the valve.
• The material to be dispensed can be supplied through tubing instead of through a syringe barrel. This tubing is
connected to the valve using an M8 x 1 cap nut.
