The advanced valve technology Valve production technology continues to develop, from the old gate valve to gate valve, butterfly valve from the initial to the wafer type butterfly valve, single eccentric, double eccentric flange butterfly valve, hard sealing butterfly valve, from the traditional single-head exhaust valve exhaust valve to the high-speed dual-orifice and so on. Therefore, when valve selection should take into account the advanced nature of the selected valve. However, application of new technologies, we oppose the indiscriminate, users do not know the actual herd approach, but should be new technology, new technology combined with user needs. Valve is in the production of good practice, directly from the user's demand comes from. For example: sealing resin extrusion method, although the design ideas and plant trials to prove its merits. However, in actual use, because the resin material, resin extrusion tools, etc., without the user how to solve the problem. Users in the use of this valve, you can not see the advanced nature of this valve, features and advantages, and used as a common butterfly. Therefore, the valve only pay attention to the nature of production, but also to focus on its usefulness. And pay attention to solve practical application problems, such as: exhaust valve of the float material, float shape (spherical or cylindrical) the effect of the exhaust and how life research. How to prevent the operation of worm gear butterfly valve control (closed off bit) problem, the top box broken gearbox problems, switch problems, and so the label instructions. Therefore, the selector valve must pay attention to its advanced technology and practicality.

阀门的生产技术不断发展，从老式的闸板阀到软密封闸阀，从最初的蝶阀到对夹式蝶阀、单偏心、双偏心法兰蝶阀、硬密封蝶阀，从传统的单头排气阀到高速双孔口排气阀等。因此选择阀门时也要考虑到所选阀门的先进性。但是，在新技术的应用中，我们反对不加区分，不了解用户实际，一哄而上的做法，而应该将新技术、新工艺与用户的需求结合起来。好的阀门是要在生产实际应用中，从用户的直接需求中得来的。例如：树脂挤压密封的方法，尽管从设计思路和工厂试验中证明其确实有优点。但是在实际使用中，由于树脂材料、挤压树脂工具等，没有解决好用户如何用的问题。用户在使用这种阀门时，就体会不出这种阀门的先进性、特点和优势，而当成普通蝶阀使用。因此，阀门生产既要关注其先进性，更要关注其实用性。并注意解决实际应用中的问题，如：排气阀的浮球材料、浮球形状(球形或圆柱形)对排气效果及使用寿命如何的研究。如何防止蜗轮蜗杆蝶阀的操作控制(关闭过位)问题，变速箱的箱体顶碎问题，开关指示的标示问题等等。所以，选择阀门一定要注意其技术的先进性和实用性。
