Description

The ARU‑R is a one‑pipe grease distribution valve that meters a fixed amount of grease discharged from the pump and delivers it sequentially to each lubrication point. When the valve completes one full operating cycle, the indicator rod moves forward and backward once. If any outlet line becomes blocked, the distribution valve will not operate, making visual detection of abnormalities quick and easy. The ARU‑R‑M type is equipped with a limit switch, allowing the operating cycle of the distribution valve to be monitored electronically and enabling detection of abnormalities through cycle‑monitoring signals.
