Pressure Reducing Valve Model Air filter pressure reducing valve is a kind of auxiliary device of pneumatic diaphragm regulating valve combination unit. After input compressed air of 0.3 ~ 1.0MPa, it can provide 0.1 ~ -1.0MPa clean air source to pneumatic remote control board and valve positioner . Pressure reducing valve air filter pressure reducing valve belongs to the pilot piston valve. The main valve and pilot valve composed of two parts. The main valve from the valve seat, the main valve disk, piston, spring and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area, to achieve decompression regulator function. This product is mainly used for gas pipeline, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases. Air filter pressure reducing valve Model Features: 1, sophisticated technology, compact structure, beautiful appearance. 2, filter pure, with PE porous filter, can be used repeatedly. 3, with dual function of air filtration decompression, pressure output is stable. 4, the key components of stainless steel material. 5, sewage water is convenient and effective. 6, aluminum alloy castings for anodized, spray the surface, strong and beautiful corrosion-resistant. 7, with the factory production of electrical converters, electrical valve positioner to achieve the integration of the factory, make installation more convenient, the structure more sophisticated and beautiful.
