Valve mounting screws

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

4 hexagon socket head cap screws 
ISO 4762-M5x50-10.9-flZn-240h-L 
(friction coefficient 0.09 - 0.14 according to VDA 235-101)

(have to be ordered separately)

Subplates

G 341/01 FE/ZN (G1/4)
G 342/01 FE/ZN (G3/8)
G 502/01 FE/ZN (G1/2)
with dimensions as in the data sheet 45052
(have to 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 are galvanized.
