主要包括各类高低压特种电动或气动阀门,主要用于高压流体介质质量流量和压力的快响应控制。
创新点:一是通过电磁阀或气动阀快速通断数十只按游标二进制比例分配面积的阀门通道,实现宽流量和压力范围介质质量流量的******调节,相对精度可达到0.1%;二是采用双音速喉道控制及流量测量技术,通过针阀控制******音速喉道面积,使第二喉道达到临界音速,测量第二喉道前总压和温度,获得所需的流量。
所达到的国内、国际水平:该技术控制测量精度达到国际******水平。

其中已形成几大类阀门如下:
一、气动伺服多缸复合高压减压调节阀(Pneumatic Servo Multi - cylinder Compound High - pressure Reducing Control Valve)

该产品属于自主研发,针对高压大流量的气流减压恒压应用开发。采用气动复合缸伺服结构,总压自励复合气动缸控制伺服,文丘里喉道配合高精度阀针,控制稳定、响应快速、控制范围宽,具有极高控制气流的可控分辨率及气流稳定性。复合自励反馈(压力和流量自励)及控制双闭环结构保证了减压后压力稳定,气体输出端流速平稳。并且,与国内同类产品相比,该产品流量大、减压范围宽、自励特性更平稳。
Our company researches this product independently, for high-pressure & large mass-flow of decompression and constant pressure application development. With the use of pneumatic compound cylinder servo structure, the total pressure self-feed composite pneumatic cylinder control servo, and Venturi throat with high-precision valve needle, make contribute to controllable resolution and high stability control flow, which is stability, fast response, wide range of controlling. The composite self-feed feedback (pressure and flow self-feed) and the control double closed-loop structure ensure the pressure stability after decompression as well as stable gas output flow. And compared with the same kind of products in domestic, it is provided with large flow, wide range of decompression, and more stable self-feed characteristics.
 该产品采用全气电伺服、高压法兰连接、不锈钢结构,外表面整洁美观,为国内首批研制。适用于高精度、快响应、大流量的气流减压控制的科研实验和高端生产领域。
The product is the first batch of domestic research and development, which adopts the whole  electric or pneumatic aservo, high-pressure flange connection, stainless steel structure. As a result, the outer surface is net and beautiful. It is suitable for  scientific research and high-end production areas of high-precision, fast response, and high-flow control of the decompression.
