Imported high pressure difference control valve
Product overview of imported high pressure differential valve
The American YLOK imported high-pressure differential control valve (also known as multi-stage pressure reduction control valve) uses the most advanced porous multi-stage pressure-reducing valve cage, suitable for high-pressure differential fluid and steam conditions, and the multi-stage pressure reduction control valve has pressure drop Features such as low loss, large flow, high accuracy of flow characteristic curve, and good dynamic stability. The multi-stage pressure reducing regulator (high pressure differential regulator) can well control the flow rate of the fluid flowing through the valve trim, so it can greatly reduce noise and effectively prevent cavitation caused by liquid. Multi-stage pressure reducing valve is mainly used in environments with cavitation, high noise and high fluid pressure difference.
Imported multi-stage pressure-reducing regulating valve adopts sleeve-oriented and balanced working pressure spool. It is a regulating valve with a novel structure. Because the valve core has cam eccentricity, it can also reduce valve seat damage and improve sealing characteristics. There is a guide wing behind the valve core, which is conducive to the smooth flow of fluid and has good stability. On the other hand, it also has the advantages of large flow rate and wide adjustment range. Suitable for friction and erosion resistant media containing solid materials and viscosity. This type of control valve can be used in places where the pressure difference is large and the working conditions are flashing and cavitation.
    According to the difference of main parameters, design multiple different pressure reducing cages to form a multi-stage pressure reducing internal part, and design the cages according to different working conditions to ensure that the flashing and cavitation problems of the valve are eliminated. The medium is throttled right after it contacts the first cage, and the high pressure difference at the inlet is gradually reduced by multiple throttling, which reasonably ensures that when the medium flows in the valve, the working pressure is always above its saturated vapor pressure. , It also eliminates the possibility of flashing and cavitation, and extends the service life of the regulating valve in * working conditions.
