当采用气动仪表时，应选用气动执行机构。气动执行机构工作可靠、结构简单、检修维护工作量小，值得推广使用。因此当采用电动仪表时，除可选用电动执行结构外，也可考虑选用气动执行机构，以发挥气动执行机构的性。当配直行程控制阀（如直通单作阀、三通阀）时，应选择气动薄膜执行机构或气动活塞执行机构。气动薄膜执行机构的输出力通常能满足控制阀的要求，所以大多数均选用气动薄膜执行机构。但当所配的控制阀的口径较大或介质为高压差时，执行机构就有较大的输出力，此时，气动薄膜执行机构应配上一个阀门定位器，或者选用气动活塞执行机构。当配角行程控制阀（如蝶阀）时就应选用长行程执行机构。但是所需输出力矩较小时，也可选用气动薄膜执行机构或气动活塞执行机构，只要再加上一个杠杆和一个支点后，便可使其输出一个力矩。
