1、aus Patentschrift Nr. 556 917,The worlds first two-line system, (HELIOS HA) today world standard, was born in our company. In 1928 we received THE patent no. 556917 for it.,The two-line system supplies the friction point with lubricant via two main lines that are alternatively pressurized. From the
2、main lines, branch lines lead to the metering devices. A change-over valve and end-of-line pressure switches ar used to alternatively pressurize and relieve the main lines.,The main parts of a two-line system are,Pipe to the friction points,Electric control box,Two-line System,End-of-line pressure s
