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.

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24.

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.

NOTE: Nordson EFD recommends installing a precision pressure regulator with a maximum control tolerance of

0.2%.
