梅索尼兰调节阀调试方法:将HART375手操器连到阀门定位器上后，启动HART375进入MANUAL模式→Calibration Menu→Tuning→AutoTune，然后定位器开始自检，待自检完毕后，退出Calibration Menu 模式，进入Normal模式即可下面举出几个具体列子：1.阀门反馈不正常解决方法：启动HART→进入MANUAL模式→Calibration Menu→Range→Autostops(手动）（校正）（菜单）（范围）（运行结束后，退出Calibration Menu模式，进入Normal模式即可（校正）（菜单）（正常）2.阀门波动大解决方法：启动HART→进入MANUAL模式→Calibration Menu→Tuning→PID coefficient（手动）（校正）（菜单）（调优）（系数）选2次OK→选择一次entet→将I值相应放大→选择enter7次后再选择一次OK，修改I参（进入）（进入）数完成。
运行结束后，退出Calibration Menu模式，进入Normal模式即可（校正）（菜单）（正常）3.零位或满位偏差大解决方法：启动HART→进入MANUAL模式→Calibration Menu→Range→Autostops(手动）（校正）（菜单）（范围）运行结束后，退出Calibration Menu模式，进入Normal模式即可（校正）（菜单）（正常）4.阀门不动作从以下几个方面检查：1）检查阀门是否送电，是否有气源和指令线是否有问题2）有手动装置的阀门检查是否阀门在手动位置3）是否用HART375调试时打到MANUAL模式，调试结束后未返回Normal模式(手动）（正常）FISHER调节阀调试方法：在调试之前首先确认阀门的Travel值（阀体上的标牌上有标注，比如1/4、3/4等），且使阀门处于初始状态（即全开或全关，根据阀门是气开阀还是气关阀而定），然后将定位器外壳螺丝松开，打开外壳取出里面的黑色小圆棒将小圆棒穿过定位器与阀杆连接部分后卡在定位器边上的小孔上，将连接部分可移动的杆放在与阀门Travel值对应的位置上，固定即可。

阀门调试梅索尼兰是一种智能式的定位器，对该种气动阀的调试，首先对控制回路查线和接线方式确认，再次对仪表管道进行吹扫。
注意事项：在进行设置时必须从信号源输入4~20mA电流信号或者从HART（数字通信协议）输入，操作电源来自于4~20mA电流信号或者是12/24VDC电压等多支路供应。
当SVI阀门调节器或控制器没有按钮或者没有显示，如果要进行系统设置或校验，则必须用HART通信协议或者个人计算机上阀门软件来进行阀门参数设定。
该定位器又分为气开式（正作用式：4mA指令对应全关、20mA指令对应全开）、气关式（反作用式：4mA指令对应全开、20mA指令对应全关）和双气缸（厂家说：出厂是什么参数就是什么不需要更改什么参数）三种型号，梅索尼兰有一个简便操作接口、高精度的阀位执行机构、据有自动设置和调整功能。
所以我们首先要认识阀门的用户接口(interface)，梅索尼兰有三个操作按钮，○1左边一个按钮上标有“*”字样，这个按钮允许我们进行选择或者确认被改的参数；○2中间这个按钮上标有“-”字样，这个按键允许我们从下一个菜单移到上一个菜单，或者对所修改的参数进行减操作；○3右边这个按钮上标有“+”字样，这个按键允许我们从上一个菜单移到下一个菜单，或者对所修改的参数进行加操作。
当我们首次调试时，第一个看到的画面是“POS…”，如果要调整该定位器，首先必须从“POS…”切换到手动位置，画面显示的是：“MAN POS”。
当阀门在自动位置时我们可以用以下方法进行切换。
首先按标记为“+”的键，只到阀门显示（→MAN）字样时，按“*”键就可以进入手动状态，在手动状态时阀门应显示（MAN POS）字样。
这时如果再按下“*”键，就可以进行手动操作该阀门。
如果想切换到自动位置时，只要该定位器显示（MAN POS）字样时，表示阀门现为手动状态。
这时我们只有按下“+”键，只到显示（→OPER）字样，这时按“*”键，阀门将会自动进入自动状态。
调节阀手册第一章概述O.P.小洛维特在现代化工厂的自动控制中，调节阀起着十分重要的作用，这些工厂的生产取决于流动着的液体和气体的正确分配和控制。
这些控制无论是能量的交换、压力的降低或者是简单的容器加料，都需要靠某些最终控制元件去完成。
最终控制元件可以认为是自动控制的“体力”。
在调节器的低能量级和执行流动流体控制所需的高能级功能之间，最终控制元件完成了必要的功率放大作用。
调节阀是最终控制元件的最广泛使用的型式。
其他的最终控制元件包括计量泵、调节挡板和百叶窗式挡板（一种蝶阀的变型）、可变斜度的风扇叶片、电流调节装置以及不同于阀门的电动机定位装置。
尽管调节阀得到广泛的使用，调节系统中的其它单元大概都没有像它那样少的维护工作量。
在许多系统中，调节阀经受的工作条件如温度、压力、腐蚀和污染都要比其它部件更为严重，然而，当它控制工艺流体的流动时，它必须令人满意地运行及最少的维修量。
调节阀在管道中起可变阻力的作用。
它改变工艺流体的紊流度或者在层流情况下提供一个压力降，压力降是由改变阀门阻力或"摩擦"所引起的。
这一压力降低过程通常称为“节流”。
对于气体，它接近于等温绝热状态，偏差取决于气体的非理想程度（焦耳一汤姆逊效应）。
在液体的情况下，压力则为紊流或粘滞摩擦所消耗，这两种情况都把压力转化为热能，导致温度略为升高。
常见的控制回路包括三个主要部分，第一部分是敏感元件，它通常是一个变送器。
它是一个能够用来测量被调工艺参数的装置，这类参数如压力、液位或温度。
变送器的输出被送到调节仪表一一调节器，它确定并测量给定值或期望值与工艺参数的实际值之间的偏差，一个接一个地把校正信号送出给最终控制元件一一调节阀。
阀门改奕了流体的流量，使工艺参数达到了期望值。
在气动调节系统中，调节器输出的气动信号可以直接驱动弹簧－薄膜式执行机构或者活塞式执行机构，使阀门动作、在这种情况下，确定阀位所需的能量是由压缩空气提供的，压缩空气应当在室外的设备中加以干燥，以防止冻结，并应净化和过滤。
