Product Description Air filter pressure reducing valve is a key component widely used in pneumatic control systems, mainly used to purify compressed air and stabilize output pressure. Structure and compositionFilter partFilter element: Usually sintered metal, ceramic or polymer material, can intercept 40 micron (or smaller) particles, oil mist and moisture.Water cup: Collects separated liquid water and impurities. Some models are equipped with manual or automatic drainage valves.Baffle design: Through the airflow rotation centrifugal force to accelerate the separation of impurities, improve the filtration efficiency.Decompression sectionDiaphragm/piston structure: Sensing output pressure changes, linkage spool adjustment opening.Adjust the spring: by rotating the hand wheel (or screw) to change the spring preload, set the target output pressure.Gauge interface: Some models are equipped with dual gauges (input/output pressure display) for easy monitoring.Additional functionOverflow hole: automatic pressure relief when overpressure, protect downstream equipment.Shock-proof design: Industrial models are often equipped with seismic pressure gauges to adapt to the vibration environment. the working principle1. Filtration stageAfter the compressed air enters, it first strikes the baffle to produce a swirl, and large particles and liquid water are thrown to the water collection cup due to centrifugal force, and then the air is further purified through the filter element.2, pressure reduction adjustmentBalanced state: The output pressure acts under the diaphragm and is balanced with the regulating spring force, and the spool maintains a stable opening.Pressure fluctuation response:Increased output pressure: the thrust on the diaphragm increases, the spring is compressed, and the spool is moved up to reduce the opening and limit the airflow.Output pressure reduction: the spring pushes the diaphragm down, the spool opening increases, and the air supply increases.Dynamic adjustment: Through the feedback mechanism to achieve automatic pressure stability, accuracy up to ±5%.3. Typical work flowAir intake (0.3-1.0MPa) → filtration (removing oil and water impurities) → decompression (adjusting to 0.1-0.7MPa) → stable output. Core functionsClean air: Protect precision pneumatic components (such as solenoid valves, cylinders) from contamination.Stabilized output: eliminate the influence of air source pressure fluctuation on the actuator to ensure consistency of action.Safety protection: Overpressure is prevented by overflow design, and some models integrate pressure switches to achieve interlock control. Application scenariosIndustrial automation: Pressure control of machine tools and assembly line pneumatic fixtures.Process control: Adjust the gas supply pressure of the valve positioner to improve the adjustment accuracy.Special environment:Food and medicine: stainless steel material, in line with health standards.Flammable environment: explosion-proof design, suitable for petrochemical industry.Mobile equipment: pneumatic braking systems for construction machinery. 1) foam packing inside,one carton box outside2) then put all carton box in one strong plywood case for sea transportPort of departure: Shanghai, ChinaLead Time:Quantity(Units)1-5051-10001001-10000>10001Est.
