Actuating function via reciprocal pressurization.
6.2.2. flow direction below the seat
Depending on the version, the valve is closed against the medium
flow with spring force (control function A, CFA) or with pilot pressure
(control function B or I, CFB or CFI).
As the medium pressure is under the control cone, this pressure con-
tributes to the opening of the valve.
Warning!
medium may be discharged if minimum pilot pressure is too
low or medium pressure too high!
If the minimum pilot pressure is too low for CFB and CFI or the
permitted medium pressure is exceeded, leaks may occur.
• Observe minimum pilot pressure.
• Do not exceed medium pressure (see chapter “Pressure ranges”).
