Product Detail

Product overview

The fixed proportional pressure reducing valve is beautiful in appearance, reliable in quality, accurate in proportion and stable in operation, reducing both dynamic pressure and static pressure. This valve utilizes the pressure difference generated by the different cross-sectional areas at both ends of the piston inside the valve body to change the pressure behind the valve to achieve the purpose of decompression.


The pressure reduction ratio of this series of proportional pressure reducing valves is: 2:1, 3:1, 4:1, 3:2, etc., and special pressure reducing valves can also be designed according to user requirements.


Scope of application

This series of pressure reducing valve series products are suitable for urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other industries.
