316 Stainless Steel Electro Pneumatic Valve Positioner Flameproof ExtD

Smart valve positioner, dust explosion-proof ExtD, angular stroke, single
acting, fail lock, stainless steel corrosion-resistant, split body anti-high
temperature vibration

High availability and easy interpretation are the key success factors in
effective field device data analysis. smart valve controllers support
standardized technologies and ensure the availability and usability of
diagnostics information independent of your control, safety or asset management
