XB Series: Side-Mounted Suction Oil Filter

This product is installed at the suction port of the oil pump, aimed to protecting the oil pump and other hydraulic components by preventing the ingestion of contaminated impurities, effectively controlling contamination and improving the cleanliness of the hydraulic system.

Self-Sealing Valve:

The filter is directly mounted on the side of the oil tank. When the filter cover is opened for filter element replacement, the self-sealing valve automatically closes to isolate the oil circuit, simplifying the oil circuit and making the filter element replacement more convenient.

Built-in Clogging Indicator and Bypass Valve

When the clogging indicator is in the green range, it indicates the filter is operating normally; when the clogging indicator is in the red range, it indicates the filter is contaminated and blocked. When the Oil outlet vacuum pressure reaches 2.7 psi (0.18 bar), the indicator sends a switch signal (changes from normally open to normally closed), indicating that the filter element should be replaced or cleaned. If immediate shutdown for replacement or cleaning is not possible, the built-in bypass valve will automatically open when the oil outlet vacuum pressure reaches 3.0 psi (0.2 bar), preventing further increase in vacuum pressure, protecting the oil from damage.
