FESTO Filter Regulator Lfr-3/4-D-Maxi-MPa 5μm Or 40μm 5~60℃
FESTO Filter Regulator Lfr-3/4-D-Maxi-MPa
Product Description
In the operation of pneumatic control valves, air filtration pressure reducing valves are an essential component. Its main function is to filter impurities in the air source and reduce the pressure of the air source to the pressure required by the pneumatic control valve to ensure the normal operation of the pneumatic control valve.
1.Good particle and condensate separation.
2. With manual, semiautomatic, or fully automatic condensate drain.
3. High flow rate with minimal pressure drop.
4. Choice of filter cartridges: 5 µm or 40µm
5. Strong pressure resistance, pressure resistance up to 1.6MPA.
6. The whole material is made of aluminum alloy, which has stable performance and durability.
7. The diaphragm has good resistance to oil and heat.
8. Double pressure scale, MPA / BAR reading is convenient and the display is more accurate.
8. Complete accessories, not easy to rust.

Working principle
The working principle of the air filtration pressure reducing valve is relatively simple, which mainly consists of four parts: filtration, pressure reduction, regulation, and emission.
1. Filtration: The first part of the work of the air filtration pressure reducing valve is filtration, which can filter out impurities such as particles in the air source.
2. Pressure reduction: Along one side of the pipeline structure, it reduces the air source pressure to within the regulated pressure, ensuring the accuracy and stability of the control of the pneumatic control valve.
3. Adjustment: The third part of the air filtration pressure reducing valve is adjustment, which involves setting the required pressure value for fine-tuning.
4. Emission: The last part of the air filtration pressure reducing valve is emission, which eliminates faults such as gas diaphragm failure caused by incomplete pressure reduction.
