Y43X fixed proportional pressure reducing valve

Y43X fixed proportional pressure reducing valve

Overview of fixed proportional pressure reducing valve: The proportional pressure reducing valve has beautiful appearance, reliable quality, accurate ratio, stable operation, and reduces both dynamic pressure and static pressure. The valve uses the pressure difference generated by the different cross-sectional areas of the piston inside the valve body to change the pressure after the valve to achieve the purpose of reducing pressure. The pressure reducing ratio of the pressure reducing valve is: 2:1, 3:1, 4:1, 3:2, 5:2, etc.
