The DPT 3 hydraulic change-over valve is used as
independent component of two-line lubricating circuits
that operate with grease and oil. The valve is suitable for
central lubrication systems with all types of two-line
distributors (e.g. DLDA, DLDC, DLDD, DLDF, ZVM) and
lubricating pumps (e.g. Z1, BEG-R, UCF, BPG).
