Smart valve positioner, dust explosion-proof ExtD, angular stroke, double acting, failsafe, split body anti-high temperature vibration
The one key self-tuning of the product can be seen in a fool's way. The commissioning can be completed in a few minutes. The built-in fault locking function does not need an external solenoid valve and a power-off comparator. The three cut-off protection positions of power-off, signal cut-off and gas cut-off of the valve can be easily realized by simply connecting an external air lock valve, saving user investment. The unique valve fixed on-line positioner replacement function effectively solves the pain point of maintaining and replacing the positioner without stopping production during the production process.
