Install a Nozzle Heater (Optional)
The nozzle heater is an optional component; however, because most solder applications require a nozzle heater,
it was included as a step under “Assemble the Valve (Initial Assembly)” on page15. This section is included for
additional reference as needed.
The illustration below shows the installation of a nozzle heater. 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 page39 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-Jet 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.
• To attach or release the heater
cable, loosen or tighten the knurled
nut by hand. Be sure to connect
the heater cable plug in the correct
orientation.

Mount the Valve
Mount the valve using either of the following options.
Standard Mounting
Secure the valve using two M3 x 25 hex screws (customer-supplied).
Four mounting holes are available to allow for adjustment.
Quick-Mounting
An optional quick-mounting bracket is available for faster valve
removal and installation. Once the valve is installed using the quick-
mounting components, it can be easily removed or installed using
the quick-release fastener. Refer to “Quick-Release Valve Mounting
Components” on page38 for the quick-mounting kit part number.
You will need the following items:
• Vibration decoupler
• Quick-release fastener
• 2 M4 hex screws (minimum length: 10 mm)
• Hex wrench, size 2.5
• Hex wrench, size 3.0

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
defines the opening time of the valve and can be set from 2 ms to infinity. 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.
