Smart valve positioner, dust explosion-proof ExtD, straight stroke, double acting, fail lock, split body anti-high temperature vibration
The control valve is the terminal of the control system, and the Smart valve positioner plays a very important role in the control performance of the entire control valve and on-site performance. The Smart valve positioner can be used in the control process of the Smart valve positioner to achieve high-quality adjustment and increase the accuracy and stability of the process control.
As the Smart valve positioner is superior to conventional valve positioners in terms of control accuracy, adaptability to the environment, commissioning, maintenance and operation costs, its practical application is becoming more and more extensive.
