Huilong low pressure filters are widely used in low pressure hydraulic systems. Different superior materials are available to make the filter to guarantee a maximum efficiency of solid contaminants removal from fluid. The differential pressure indicator and bypass valve are optional upon request.

The clogging indicator actuates and outputs electrical a warning signal when the clogging of the filter element causes an increase in pressure drop, reminding you to replace the filter element. If the filter element hasn’t been replaced, once the differential pressure reaches the opening pressure of the bypass valve, it will open and allow the unfiltered fluid to flow through to the downstream system.
