12.2 High-Pressure Spindle
12.2.2 Application / Function
The HDS high-pressure spindle is used for simplified adjustment of the control spring
in the gas pressure regulator. For the adjustment of particularly strong control springs,
the use of a high-pressure spindle is mandatory. (See p. 16 - 17.)
12.2.1 Use
• Gas pressure regulators RS 250 / RS 251
• Gas pressure regulators RS 254 / RS 255
• Gas pressure regulators R 100 / R 100-U
• Gas pressure regulators R101
12.2.3 Mounting
• Unscrew the sealing cap
• Unscrew the setting screw anticlockwise
• Take off the spring plate from the spring
Attention! Do not lose the steel ball!
• Remove the built-in spring
• Insert a new spring
• Insert spring plate again
Attention! Do not forget the steel ball!
• Screw high-pressure cap with high-pressure spindle
into the spring dome
Do not forget the O-ring!
