YB43X proportional pressure reducing valve is beautiful in appearance, reliable in quality, accurate in proportion, smooth in operation, reducing both dynamic and static pressure. The pressure reducing valve utilizes the pressure difference generated by the different carrier areas at both ends of the piston inside the valve body to change the pressure behind the valve and achieve the purpose of pressure reduction. The pressure reducing ratio of proportional pressure reducing valve is 2:1, 3:1, 4:1, 3:2, 5:2, etc. Special proportions can also be designed according to customer requirements.
Product Characteristics
