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.
