Two-line systems essentially consist of a pump, a directional control valve, two main lines, two-line distributors and a switching device. As the two-line distributor has two main lines, the use of so-called cyclical lubrication is needed to alternately pressurise the. Use to control 2 groups of luminaires independently of each other (same circuit, separate control) or to control 2 individual circuits of luminaires (2 protective devices at the distribution board (s) - must be the same phase). Even if one pair of outlets becomes blocked inside one metering device, dual-line systems provide sufficient lubrication for the rest of the. Quick Answer: Dual-line lubrication systems use two main supply lines alternating pressure to operate large divider valves serving 100-1000+ lube points. Operating at 25-40 MPa, they're ideal for heavy industry (mining, steel, cement) with long pipe runs (up to 300m). Each point can be individually.
