LXZS With Check Valve Magnetic Return Filter
Product Overview
LXZS With Check Valve Magnetic Return Filter is a vital FILTER installed on the hydraulic oil tank. It cleans return oil flowing back to the tank in the hydraulic system. Equipped with permanent magnet and built-in check valve, this FILTER captures iron wear particles and solid contaminants. The check valve prevents oil backflow when the Machine stops, protecting the hydraulic system and hydraulic components. It is widely used for engineering Machine, mining equipment and hydraulic power units.
Technical Specifications
- Rated flow: 25 ~ 630 L/min
- Max working pressure: 1.6 MPa
- Filtration accuracy: 3μm,5μm,10μm,20μm,30μm optional
- Bypass valve opening pressure: 0.3~0.4 MPa
- Medium: mineral hydraulic oil, water-glycol emulsion
- Working temperature: -10℃ ~ +100℃
- Installation: tank top mounting, with integrated check valve
Working Principle
Return oil enters this FILTER before flowing into the tank. The permanent magnet adsorbs fine ferrous debris, then the filter element traps other solid impurities. When the FILTER gets clogged, the bypass valve opens to maintain operation of the hydraulic system. The built-in check valve cuts off oil reverse flow once the Machine shuts down, avoiding contaminated oil re-entering the hydraulic circuit.
Core Advantages
1. Dual purification structure: magnetic adsorption + filter element filtration, keeps hydraulic system oil clean.
2. Integral check valve design, prevents oil backflow after Machine shutdown.
3. Built-in bypass valve, protects the Machine when FILTER is blocked.
4. Large dirt holding capacity, low pressure drop, stable running performance.
5. Easy filter element replacement, simple maintenance for hydraulic system.
Application Range
This FILTER fits multiple types of Machine, including construction machinery, agricultural machines, metallurgical and mining equipment, hydraulic stations. It effectively reduces abrasion of pumps, valves and cylinders inside the hydraulic system.
