Product description
The 10D00 Series multi-hole low noise control
valve adopts the cage guided structure and pressure balanced plug. It is a high
performance control valve with good dynamic stability that is suitable for
severe service conditions. As the differential pressure in the service
conditions is relatively high and the flow velocity of media is high, the trims
will be severely eroded and damaged and high noise will be produced. Therefore,
we change the standard window-type cage into the multi-hole cage. For liquids,
the flow direction is generally high-in and low-out, and multi-hole throttling
makes the media carry out collision inside the cage, so as to consume internal
energy and reduce flow velocity. For gas media, the flow direction is generally
low-in and high-out, so that the gas media achieve volume expansion at the back
of the seat after throttling by the multi-hole cage and the pressure of media
is reduced to lower the flow velocity. The parts of the 10D00 Series are
interchangeable with those of the 10T00 Series except that the cage is changed
into the multi-hole type.
