Features and advantages
EV2000 series of regulating valve body by
double sealing metal and elastic material, adopting axisymmetric shape design,
so that the valve cavity flow area is always ring contraction, avoid throttling
the exit to the axis, eliminating cavitation and vibration of pipelines and
pipeline damage. Ideal for geometric design, the fluid is well guided within
the streamline body. Even in the case of high pressure, the Cone Fix Valve can effectively eliminate the differential pressure, the pressure
reduced to low pressure, and will not produce vibration and cavitation
phenomenon. From the entrance to the contraction section of the annular flow
area of the continuous decline in the flow rate gradually increased, without
cavitation, without cavitation damage energy conversion. Regardless of the
position of the piston, the flow profile is annular, thus ensuring a perfect
linear regulation characteristic.
