确保调节阀可靠的操作性，这里不仅指调节阀本身的制造质量，还涉及到调节阀的正确计算、调节阀选型，以及包括对操作人员的培训和素质的提高。为了防止误操作，工艺人员一定要注意铭牌所标的注意事项，根据我国新气动调节阀新标准（GB/T4213—92），执行机构的铭牌至少要标出制造厂名、产品型号、额定流量系数、设计位号、产品编号及制造年月等项；阀体上则要铸出或冲出表示介质流动方向的箭头和“DN”数值以及“PN”的字样及数值，也可以标志在与阀体牢牢固定的铭牌上。重要的调节阀都要装有足够的附件，如阀门定位器、极限开关等。要有足够的安装空间和操作空间，有足够的照明，有严格的操作规程。 为了保证调节阀的质量，调节阀的选用要经过正确的计算；类型、口径、各项性能都要符合要求；调节阀各种重要零件的材料要严格的挑选；要有足够的强度和刚度；要按照国家标准通过耐压试验，气密性等试验；生产厂家的制造技术和测试方法必须符合标准，要由主管部门鉴定认可。

原文：
To ensure reliable operational control valve, control valve itself here refers not only to manufacturing quality, but also to the correct calculation of control valve, control valve selection, and includes operator training and quality. To prevent misuse, craft workers must pay attention to the subject plate note, the new pneumatic valve under our new standard (GB/T4213-92), executive body of the plate at least to mark the manufacturer name, model number, rated flow coefficient design-bit number, product number and year of manufacture other items; the valve body will have to cast out or out of that medium flow direction arrows and "DN" value and "PN" in the words and values, you can sign in with the valve plate firmly fixed on the body. Important regulator valveshould be equipped with enough accessories, such as valve positioners, limit switches. Have sufficient space for installation and operation, adequate lighting, strict operational procedures. To ensure quality control valve, control valve selection to go through the correct calculation; type, caliber, every performance must meet the requirements; various important parts valve strict selection of materials; have sufficient strength and rigidity; In accordance with the national standard through the pressure test, air tightness and other tests; manufacturers manufacturing techniques and testing methods must conform to standards, to be approved by the competent authorities identified.
