Proportional pressure reducing valve, which has beautiful appearance, reliable quality, accurate proportion and stable operation. The valve using the piston at both ends of the piston at both ends of the pressure generated by different cross-sectional area, the pressure to change the valve to achieve the purpose of decompression. The ratio of pressure relief valve in our factory is: 2:1, 3:1, 4:1, 3:2, S 2, etc., can also be designed according to the requirements of the user's special proportion of the pressure reducing valve.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
