Valve mounting screws

For reasons of stability, exclusively use the following valve mounting screws:

2 hexagon socket head cap screws ISO 4762-M6x60-10.9-flZn-240h-L

(friction coefficient total: 0.09-0.14 according to VDA 235-101)(must be ordered separately)

4 hexagon socket head cap screws ISO 4762-M10x60-10.9-flZn-240h-L

(total friction coefficient: 0.09-0.14 according to VDA 235-101)(must be ordered separately)Important:

Subplates are no components in the sense of directive 94/9/EC and can be used after the manufacturer of the overall system has assessed the risk of ignition.

The G...FE/ZN versions are free from aluminum and/or mag-nesium and galvanized.
