ZKY13X Proportion Pressure Reducing Valve is one type of adjusting valves which reduce the medium pressure proportionally. It is usually applicable to high building, pump station and fire fighting system. It has nice outline, reliable quality, and accurate proportion, smooth operating. It can reduce both dynamic pressure and static pressure. The two ends of valve piston have different sectional area which will bring differential pressure to change the pressure after valve, achieving the pressure reducing.
ZKY13X Proportion Pressure Reducing Valve pressure reducing proportion is 2:1, 3:1, 4:1, 3:2, 5:2, and also we can design special proportion according to the customer’s requirements. It is applicable to be mounted on the pipeline (≤DN65).
