对执行机构输出力确定后，根据工艺使用环境要求，选择相应的执行机构。对于现场有防爆要求时，应选用气动执行机构。从节能方面考虑，应尽量选用电动执行机构。若调节精度高，可选择液动执行机构。如发电厂透明机的速度调节、炼油厂的催化装置反应器的温度调节控制等。
调节阀的作用方式只是在选用气动执行机构时才有，其作用方式通过执行机构正反作用和阀门的正反作用组合形成。组合形式有4种即正正（气关型）、正反（气开型）、反正（气开型）、反反（气关型），通过这四种组合形成的调节阀作用方式有气开和气关两种。
对于调节阀作用方式的选择，主要从三方面考虑：a）工艺生产安全；b）介质的特性；c）保证产品质量，经济损失最小。电动调节阀、压力调节阀、单座调节阀、气动调节阀、套筒调节阀、双座调节阀、三通调节阀、温度调节阀、风量调节阀、自力式调节阀、防火调节阀、分流调节阀、手动调节阀、笼式调节阀、微压调节阀、精小型调节阀、角形调节阀、回转式调节阀、多叶调节阀、差压调节阀、直通调节阀、电子式调节阀、合流调节阀、密封调节阀、

调节阀的维护与一般仪表的维护类似，可分为被动性维护、预防性维护和预见性维护。被动性维护是当调节阀等设备出现故障时才进行维护的一种维护方法。由于设备发生故障才维护，因此常常造成生产过程停车，严重时甚至出现设备损坏或人员伤亡等。被动性维护是生产过程所不希望的维护，

预防性维护是根据过去的运行经验，按时间进行维护的一种维护方法。例如，常用的定期维护就是预防性维护，它根据不同设备的运行情况制定相应的维护时间表，在设备还没有出现故障时就进行维护。由于故障没有发生就进行维护，因此，可大大降低故障发生概率。但这种维护方法并没有将当前使用的该调节阀实际情况进行分析，常常对还可以使用一定时间的调节阀进行拆装和检查，浪费了时间和资源。预见性维护从当前使用的调节阀数据分析出发，预见该调节阀的状态，从而使调节阀得到最大限度的利用。

10、做好巡回检查的记录，并归档。
定期维护工作内容如下：
1、定期对调节阀外部进行清洁工作。
2、定期对调节阀填料函和其他密封部件进行调整，必要时应更换密封部件，保持静、动密封点的密封性。
3、定期对需润滑的部件添加润滑油。
4、定期对气源或液压过滤系统进行排污和清洁工作。
5、定期检查各连接点的连接情况，腐蚀情况，必要时应更换连接件。
二、 调节阀的定期校验
调节阀预见性维护工作尚未开展的单位，应对调节阀进行定期校验。定期校验工作是预防性维护工作。
根据不同工艺生产过程，调节阀的定期校验应有不同的校验周期。可结合制造商提供的资料确定各调节阀定期校验的周期。通常可在工艺生产过程进行大修的同时进行。一些调节阀应用在高压、高压降或腐蚀性较强的场合时，检验周期要缩短。
检验的内容主要是调节阀静态性能测试，必要时可增加相应的测试项目，例如调节阀流量特性的测试等。定期校验需要有关测试设备和仪器，还需要有更换的部件，因此，通常可委托制造厂商完成。
