Precision Jetting Valve Systems
PICO / Liquidyn
Nordson EFD jet valve systems offer unparalleled speed and
accuracy in non-contact dispensing, even for your most
challenging applications.
Jetting, or non-contact dispensing, allows manufacturers to
dispense small amounts of uids at faster speeds without
sacricing accuracy. The results include reduced waste,
rework, and rejects, and higher throughput yields.
About Piezo Technology
PICO
®
jet valves incorporate a piezoelectric actuator
composed of stacked ceramic coins that expand and
contract in response to changes in voltage supplied by the
PICO controller. The piezo actuator connects to a vertical
rod that mates with a tappet stem within a spring-energized
“jetting” cartridge. The tappet stem has a wear-resistant
ceramic sealing ball at its lower end.
When the valve is closed, the ball is seated in the valve
nozzle plate to prevent uid ow between cycles. The
unique precision engineering and machining of these critical
components create an exceptional dispensing valve with the
ability to apply precise, accurate micro-deposits of assembly
uid.
When voltage is applied to the actuator, the rod and cartridge
sealing ball are raised so that the pressurized uid can ow to
the nozzle. When the voltage is changed, the rod and tappet
stem sealing ball descend rapidly to “jet” the uid out of the
nozzle and onto the substrate.
Pneumatic Jetting
Liquidyn
®
pneumatic jet valves deliver precise, consistent
noncontact dispensing of low- to high-viscosity uids and
feature easily exchangeable dispensing nozzles to meet a
wide range of application requirements. Rigorously tested to
withstand highly-industrial environments, Liquidyn pneumatic
jet valves also feature a low cost of ownership.

PICO Pμlse Jet Valve
7361283 PICO Pμlse Jet Valve HD
For heavy duty applications with cycle rates greater
than 250Hz.
PICO
Pµlse
®
modular jetting technology removes the barrier between speed and
accuracy. Even at max speed of 1000Hz continuous*, the PICO Pµlse non-contact
dispense valve provides industry-leading accuracy in deposit consistency and
placement for your most challenging applications.
Non-contact jet valve systems make it possible to apply uid in hard-to-access areas
or onto uneven or delicate substrates where a dispensing needle cannot be used.

PICO Jetting Systems
Features and Benets
XP self-regulating calibration
Improve valve-to-valve dispensing
repeatability and repeatability after
maintenance
Maintain dispensing repeatability
regardless of environmental conditions
System self-adjusts to minimize
production downtime needed to
recalibrate the jetting system
PICO Pμlse XP Jet Valve
7364876 PICO Pμlse XP Jet Valve HD
For greater dispensing repeatability and ability to
fine tune jetting performance.
PICO
Pµlse XP provides the same capabilities as the standard PICO Pµlse jet valve.
In addition, it controls for the slightest variation in uid body tolerances to maintain
optimal jetting results, even after maintenance.
Sustained stroke target seeking allows the system to produce a stable deposit weight,
even when environmental conditions change.
