3 SAFETY, WARNING
These products are intended for use in industrial compressed air or hydraulic systems only. Do
not use these products where pressures and temperatures can exceed those listed under
‘Technical Data’.
Before using these products with fluids other than those specified, for non-industrial
applications, life-support systems, or other applications not within published specifications,
consult NORGREN. Through misuse, age, or malfunction, components used in fluid power
systems can fail in various modes. The system designer is warned to consider the failure modes
of all component parts used in fluid power systems and to provide adequate safeguards to
prevent personal injury or damage to equipment in the event of such failure.
System designers must provide a warning to end users in the system instructional
manual if protection against a failure mode cannot be adequately provided. System
designers and end users are cautioned to review specific warnings found in instruction sheets
packed and shipped with these products.
Specific warnings:
• Check if classification of the valve island and marking on the item of equipment are able for
case of operation.
• Check technical data, such as operating pressure, voltage level, current type and
temperature, on the product label or in the data sheets for compliance with the existing
operating conditions.
• After removing the packaging, make sure that no contamination enter into the system.
• Check before the installation of the system that no contamination exists in the piping and
valve island.
• Check during installation of the system that gaskets will not become damaged.
• Please consider the information of this operating manual as well as the use conditions and
permissible data, which are on the product labels.
• Adapt to the general rules of technology when selecting and using an item of equipment.
• Take measures to avoid unintentional or improper activation.
• Prior to the first electrical operation, ensure no danger would result from the medium
exhausting from any open ports.
• Consider in case of pressurised systems that lines, valves and other components should not
be removed.
• ATTENTION: There is some risk of injury! The surface of pilot valves could become very
warm in continuous operation.
• ATTENTION: Valves with NO function (normally open) are open without pilot pressure.
During commissioning, protection against exhausted medium has to be provided.
• Leak and strength tests on open and closed valves are admissible until max. 1.5 times the
max. operating pressure. It is not allowed to operate the valve during these tests.
• Never use the valve island as lever arm or a step for climbing.
• Protect the valve island from falling objects.
VS2672926-KG00E_05/07 Page 6/97

VS18/VS26 MAINTENANCE & INSTRUCTION BOOKLET
• Any fitting position of the valve island is permissible but valves with indicating lights up is
preferred.
• To avoid damaging the product, please make sure that the maximum torque values are not
exceeded (see section 5.1.2).
• Avoid short-circuits and breaks by not deviating from the standard use of connector cables
and cords.
• Order spare parts with the part number indicated on the product labels. (See section 5.2.2
and/or data sheets 5.4.159 (VS18) resp. 5.4.160 (VS26)).
• Do not load the system by bending or torsion.
• Important: Power must be removed from the system while assembling and disassembling
electrical connectors, plugs and cables, valves, sandwich plates and blanking plates.
• Install and use only complete configured and connected valve islands.
• VS18/VS26 Fieldbus valve islands contain electronic devices, which could be damaged
through electrostatic discharge. Therefore electrostatic precautions must be taken.
Specifically, the person assembling or configuring the valve island must be connected to an
earth ground.
• Please refer to section 4.4.3 for information on power supply and earth ground connection of
Multipole and Fieldbus valve islands.
• Use this booklet or the instruction sheets packed with the product for assembling and
installation.

4.3.3 Maximum cycling rate
In practice the cycling rate should be lower than 300 c.p.m. (<5 Hz). The valves should be
switched above 90% (working port) and below 10% (exhausting port) of the supply pressure.
4.3.4 Minimum impulse on bistable valves
The minimum impulse length on 5/2 way bistable valves should correspond at least twice to the
response time (see section 4.3.1).
4.3.5 Important information for 2x2/2 valves
All 2x2/2 functions (NC, NO or NO/NC) have port 1 not connected in neither end position to port
2 or 4. Port 1 is not necessary (except internal pilot air). Supply of compressed air or vacuum
must be feeded to port 3 or 5.
Pay attention to this when configuring the valve island (blanking off canals 3 and 5 in base) !!

4.4.1 Voltage tolerances
Voltage Voltage tolerances
24V DC +/-10%
115V AC -10%/+15%
4.4.2 Required performance of power supply unit
The required performance can be calculated from the maximum number of energized solenoids
at the same time. In case of a Fieldbus valve island the consumption of power of the electronic
has to be considered (see section 8).
4.4.3 Power supply and precautions
All VS18/VS26 24V DC products are designed to be used with a protective extra low voltage
(PELV) power supply (UL Class 2 Supply only).
All VS18/VS26 115V AC products correspond to the protection class I. Connection of the
protective earth (PE) ground is required.

5.1 INSTALLATION
5.1.1 Tools
VS18:
• Hexagon wrench key 2mm
• Hexagon wrench key 2.5mm
• Socket screw key X10
• Philips screwdriver size 1
• Screwdriver size 1
VS26:
• Hexagon wrench key 3mm

5.1.2 Tightening torque
To avoid damaging the product, please make sure that the maximum torque values are not
exceeded. The maximum torques are specified in the particular installation instructions.
Valve mounting screws
The valve mounting screws are pressurised. To prevent leakage through the mounting screws,
screws with blue coated thread are used. The specified torques for the blue coated screws
reduce to standard values after first use of the screws. These screws should not be used more
than five times, as good sealing performance can then not be guaranteed.

Exhaust 3 + 5
Outlet 2 + 4
External pilot air supply (if used) 12/14
Collected exhaust of pilot valves 82/84
Note:
Never plug port 82/84. Plugging this port will cause valves to malfunction.

5.1.4 Assembly of VS18/VS26 valve islands
Tools:
VS18: Hexagon wrench key 2.5mm
Philips screwdriver size 1
VS26: Hexagon wrench key 3mm
Philips screwdriver size 1
To assemble a complete valve island, make sure you have ordered all necessary components
and the required tools are available.
1. First bolt all modular sub-bases together. Ensure sub-bases are properly aligned and the
gasket is fitted between the sub-bases. Then tighten the mounting screws (two per modular
sub-base) with the specified torque. If you are using a power screwdriver, consider the
maximum speed allowed.
For multi pressure applications, please refer to section 5.1.7.
Note:
When ordering an even number of stations, please ensure the valve island contains a
maximum of two single station modular sub-bases. E.g.: You order an 8-station Multipole
valve island with an 8-station main PCB. The valve island must have at least three double
station modular sub-bases and must have no more than two single station modular sub-
bases.
When ordering an odd number of stations, the single station modular sub-base should be at
the right end of the valve island. In addition, you can use two additional single station
modular sub-bases, for a total of three.

2. Mount the left and right end plate to the modular sub-base. Ensure end plates are properly
aligned and the end plate gasket is fitted. Then tighten the mounting screws (two per end
plate) with the specified torque. If you are using a power screwdriver, consider the maximum
speed allowed.

4. Lastly, mount the valves, sandwich plates, blanking plates and/or intermediate
supply/exhaust modules.
Valves:
1. Ensure valve body gasket is fitted on the bottom of the valve. Place valve onto the
modular sub-base aligned to the interface. Use plug-in connection as positioning point.
2. VS26 only: Orientate straight flange of the U-washers towards the outer edge of the
valve.
3. Tighten the valve mounting screws (two per valve) with the specified torque. If you are
using a power screwdriver, consider the maximum speed allowed.

Blanking plate and/or intermediate supply/exhaust module (ISEM):
1. Ensure gasket is fitted on the bottom of the blanking plate or ISEM. Place blanking plate
or ISEM onto the modular sub-base aligned to the interface.
2. Tighten valve mounting screws (two per blanking plate/ISEM) with the specified torque.
If you are using a power screwdriver consider the maximum speed allowed.
