Smart valve positioner, dust explosion-proof ExtD, angular stroke, double acting, fail lock, stainless steel corrosion-resistant
Smart ( intelligent, digital) valve positioners perform the same basic functions as a traditional valve positioner, but they have expanded functionalities. The International Society of Automation (ISA) does not differentiate between traditional and smart positioners in its standards. Like any “smart” device, a smart positioner includes a small computer that enables additional capabilities. A smart positioner is analogous to a smartphone, while a traditional positioner is like your landline — both can make calls, but one can do considerably more.
The capabilities beyond positioning are what make smart positioners unique and valuable, but also what can make them intimidating. Smart positioners make the basic positioning functionality across your plant more accurate and reliable. Every positioner can be calibrated exactly the same and that calibration can be maintained, which provides more accurate control to setpoint and thus optimum process control.
