From this Article:
In the succeeding stage of the regulating valve, the secondary pressure is set as a load resistance by a regulating valve when the valve remains closed (0 flow). In the case of a backpressure valve,... (View Full Article)

From this Article:
The CV value of a needle valve changes as shown in the GRAPH2 when the valve opening changes. Setting aside the control characteristics, the problem is the flow rate, not selection of an actual valve.... (View Full Article)

From this Article:
The regulating valve controls the outlet side pressure so that it will be constant when the supply-side pressure changes. It is frequently used in the initial stage of a system.... (View Full Article)

From this Article:
Our mechanical valves can be used for gas flow control in many ways. An example of the most popular method of constant flow control with a needle valve and flow controller is explained here. The... (View Full Article)

From this Article:
A mass flow meter measures the mass flow irrespective of pressure and temperature. When representing mass by the flow, it is necessary to use units such as g/min and kg/min which are different from... (View Full Article)

From this Article:
Gas flow meters can be roughly divided into volume flow meters and mass flow meters. Volume flow meters include area flow meters, positive displacement flow meters, and differential pressure flow... (View Full Article)

From this Article:
The valve installed in a flow meter causes a pressure loss, generating a difference between the inlet pressure and outlet pressure. As shown on page 50, the reading of a fl oat type flow meter differs... (View Full Article)
