PLF High Pressure Line Filter
Product Overview
sure Line Filter is a heavy-duty inline FILTER, installed directly on the pressure pipeline of the hydraulic system. It is designed to remove solid contaminants, metal wear particles and impurities from pressurized hydraulic oil, protecting precision hydraulic components for all types of industrial and mobile Machine. This robust FILTER is widely preferred for servo circuits and high-precision hydraulic equipment, effectively preventing valve blockage and component abrasion caused by polluted oil.

Working Principle
As a core FILTER in the pressure pipeline, pressurized hydraulic fluid flows into the housing and passes through the filter element inside. Solid particles are trapped by the filter media to clean the oil in the hydraulic system. When the filter element is clogged and pressure difference rises to the set value, the differential pressure indicator sends an alarm signal. If pressure exceeds threshold, the built-in bypass valve opens automatically to avoid oil supply interruption and protect the whole Machine from sudden shutdown damage.
Core Advantages
1. High filtration efficiency with stable beta ratio ≥200, excellent protection for precision parts of the hydraulic system.
2. Compact heavy-duty housing structure, suitable for high pressure working condition of heavy-duty Machine.
3. Integrated bypass valve and clogging indicator for real-time monitoring of the FILTER status.
4. Large dirt holding capacity, long service life of filter element, low original pressure drop.
5. Easy element replacement, simple maintenance without dismantling the whole pipeline.
Application Range
This PLF FILTER is widely fitted in the hydraulic system of mining machinery, metallurgical equipment, concrete machinery, marine deck equipment and other heavy-duty Machine. It is commonly used in hydraulic power units, servo control systems and construction machinery pressure lines to keep hydraulic oil clean and extend the service life of pumps, motors and valves.
