MS6(N)−SV
Switch−through pressure
The flow control screw in the cover generates a gradual pressure build−up of output
pressure p2. The pressure rise can be adjusted by turning the flow control screw.
Once output pressure p2 reaches approximately 50 % of operating pressure p1, the
valve opens and the full operating pressure p1 is reached at the output.

Example:
If operating pressure p1 = 4 bar, a switch−through pressure of 1.2 to 2.8 bar is
permissible, given the maximum permitted tolerance of ±20 %.
