Switch-through pressure/filling time
The flow control screw in the cover generates a gradual pressure build-up of outlet pressure p2. The
pressure rise can be adjusted by turning the flow control screw. When the outlet pressure p2 reaches
about 50% of the operating pressure p1, the valve opens and the maximum flow rate performance is
enabled.

Example:
At an operating pressure of p1 = 4 bar with reference to the approved tolerance of ± 20% a switch-
through pressure of 1.2 to 2.8 bar is permissible.
