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 contributes 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.
