The factory production of proportional valve, beautiful appearance, reliable quality, accurate, steady work, both under pressure and anti-static pressure. The valve uses the valve body internal cross-sectional area of the piston at both ends of the pressure difference, changing the pressure after the valve to achieve decompression purposes. I decompression valve factory decompression ratio: 2: 1,3: 1,4: 1,3: 2,5: 2, etc., can also be designed according to the requirements of the user a special proportion of the valve.
