当控制阀专业人士在谈及"控制阀尺寸(Control Valve Sizing)",指的是选用合适的阀门来适用于控制过程。 选择大小适宜的阀是一个重要的过程的一部分,但也还有其他一些同样重要的考虑因素。 控制阀的大小应选择操作范围在60%和80%开度所需大的流量和不低于20%开度所需的小的流速。我们的想法是尽可能多地使用阀门...
When it comes to sizing a level control valve, there are several factors to consider such as the type of media being regulated, flow rate requirements, pressure drops, and line size/length. Proper selection is critical for having an effective system and

For most systems, in order to get good control with stability throughout the full range of required flow rates, we need to use a control valve that has an installed flow characteristic that is linear, or at least as close to linear as possible. It is often difficult to compare the ...
Before discussing the sizing of control valves for steam systems, it is useful to review the characteristics of steam in a heat transfer application. Steam is supplied at a specific pressure to the upstream side of the control valve through which it passes to a heat e...
