Explosion-Proof Smart Valve Positioner Single Acting Fail Lock ExdIICT6 C45GY-LSB
Smart valve positioner, flameproof explosion-proof Exd, straight stroke, single acting, fail lock, stainless steel corrosion-resistant
After the intelligent valve positioner is installed on site and the supporting valves, it must go through the self-tuning mode to obtain the stroke size of the valve, and then the characteristic parameters can be controlled. In this self-tuning process, the valve needs to be opened and closed repeatedly. The time spent depends on the performance of the valve. The short time is 3-5 minutes and the long time is more than 10 minutes. This is not allowed on the production line, which may affect the product quality or cause major safety accidents. Therefore, the on-line replacement of the positioner in the production site is a pain point for users. Torleo intelligent valve positioner adopts the principle of parameter backup, which solves this problem very skillfully.
