Ideally suited for most quarter - turn valves , nibco nda and nsr pneumatic actuators offer exceptional starting and ending torque in a compact design 适用于大多数角行程阀门,使用程度理想,美国尼伯科nda和nsr气动执行机构在紧凑的结构里提供非常的开启和关闭扭矩。
By means of the step control of pmsm , it can offer accurate and reliable position control for the angle travel terminal equipment . step angle is small , torque is large and inertia is small . this system will promote the technical guideline and control accuracy of the flow and pressure control 利用永磁同步电动机的步进控制,为角行程终端设备提供准确可靠的定位控制,步进角小、转矩大、惯量小,将使流量及压力控制达到高的技术指标和控制精度。
