10d Series Control Valve

Outline
The 10D Series multi-hole low noise control valve adopts the sleeve 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 differentia l 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 sleeve into the multi-hole sleeve. For liquids, the flow direction is generally high-in and low-out, and multi-hole throttling makes the media carry out collision inside the sleeve, 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 sleeve and the pressure of media is reduced to lower the flow velocity. The parts of the101D Series are interchangeable with those of the 101T Series control valve except that the sleeve is changed into the multi-hole type.
