Smart valve positioner, dust explosion-proof ExtD, straight stroke, single acting, fail lock, stainless steel corrosion-resistant, split body anti-high temperature vibration
In the process of production, the control valve is the terminal of the control system. Once it fails, it will directly affect the safe operation of the device and have a significant impact on the production process. Using the intelligent control valve positioner can improve the flow characteristics and performance of the control valves. Through digital information, communication with the DCS or BUS equipment can improve the enterprise’s production control ability and guarantee the safe and stable production of the device.
