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-qualified 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 micro-
deposits 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 efficiently 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 configurable. Many choices for
the material supply components and the nozzle are available, including
an optional nozzle heater.
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 fluid 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 customer-
supplied controller or a programmable logic controller (PLC).

Nordson EFD Product Safety Statement
READ MANUAL
Read manual for proper use of this equipment. Follow all safety instructions. Task- and equipment-
specific warnings, cautions, and instructions are included in equipment documentation where
appropriate. Make sure these instructions and all other equipment documents are accessible to
persons operating or servicing equipment.
The safety message that follows has a WARNING level hazard.
Failure to comply could result in death or serious injury.
WARNING
ELECTRIC SHOCK
Risk of electric shock. Disconnect power before removing covers and / or disconnect, lock out, and
tag switches before servicing electrical equipment. If you receive even a slight electrical shock, shut
down all equipment immediately. Do not restart the equipment until the problem has been identified
and corrected.
MAXIMUM AIR PRESSURE
Unless otherwise noted in the product manual, the maximum air input pressure is 7.0 bar (100
psi). Excessive air input pressure may damage the equipment. Air input pressure is intended to be
applied through an external air pressure regulator rated for 0 to 7.0 bar (0 to 100 psi).
RELEASE PRESSURE
Release hydraulic and pneumatic pressure before opening, adjusting, or servicing pressurized
systems or components.
BURNS
Hot surfaces! Avoid contact with the hot metal surfaces of heated components. If contact can not be
avoided, wear heat-protective gloves and clothing when working around heated equipment. Failure
to avoid contact with hot metal surfaces can result in personal injury.
The safety messages that follow have a CAUTION level hazard.
Failure to comply may result in minor or moderate injury.
CAUTION

Nordson EFD Product Safety Statement (continued)
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components.
Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage.
Halogenated hydrocarbon solvents contain one or more of the following elements.
Element Symbol Prefix
Fluorine F “Fluoro-”
Chlorine Cl “Chloro-”
Bromine Br “Bromo-”
Iodine I “Iodo-”
Check the Safety Data Sheet (SDS) or contact your material supplier for more information. If you must use
halogenated hydrocarbon solvents, contact your EFD representative for compatible EFD components.
High Pressure Fluids
High pressure fluids, unless they are safely contained, are extremely hazardous. Always release fluid pressure before
adjusting or servicing high pressure equipment. A jet of high pressure fluid can cut like a knife and cause serious
bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning.
WARNING
Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury:
• Go to an emergency room immediately.
• Tell the doctor that you suspect an injection injury.
• Show the doctor the following note.
• Tell the doctor what kind of material you were dispensing.
Medical Alert — Airless Spray Wounds: Note to Physician
Injection in the skin is a serious traumatic injury. It is important to treat the injury surgically as soon as possible. Do
not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the
bloodstream.
Qualified Personnel
Equipment owners are responsible for making sure that EFD equipment is installed, operated, and serviced by
qualified personnel. Qualified personnel are those employees or contractors who are trained to safely perform
their assigned tasks. They are familiar with all relevant safety rules and regulations and are physically capable of
performing their assigned tasks.
