标准的截止阀，虽然结构上适用于节流和关闭，但是不能在小于10%的开启度下长期节流使用。
Standard globe valves, because they are designed for both throttling and shutoff, should not be used for prolonged throttling at less than 10% open.

早期的设想是用计算器来计算包括截止阀和换色涂抹装置在内的仪器，然而这项设计最终才用了自动弹跳机理结构，原因是易于操作。
Early ideas to counter these issues included cut-off valves and colour-changing paint, but the designer settled on the pop-up mechanism, because of its ease of use.
