Webpressure will reposition the pilot regulator resulting in a different flow rate through the pilot. For example, in Figure 9(a) should there be a decrease in downstream pressure, the pilot regulator will open to meet the load. The pilot can allow more fluid through its orifice than the fixed orifice will allow and therefore the pressure

WebIn flow control applications, orifice plates are used as restriction devices to regulate fluid flow or reduce the flowing pressure downstream of the orifice plate. The use of a fixed restriction orifice can be beneficial and economic by reducing the demands on other flow system components. How does an orifice control flow? WebAug 23, 2024 · Compared to the flow-measuring orifice and due to the high pressure drop, the sizing of RO is more critical, and there are many parameters to consider. Pressure-controlling application The restriction orifice plate is mostly applied in noncritical flow limitation, and it is used in pipelines where a known/fixed pressure drop is required.
