Pneumatic Positioner By Application
FAQ
A: Use a positioner when you need to modulate flow (0-100%) precisely, rather than just On/Off control.
A: It is the industry standard: 4mA closes the valve, and 20mA fully opens it (or vice-versa).
A: For smart positioners, simply press the “Auto-Cal” button. For analog ones, adjust the zero and span screws.
A: Yes, our smart (digital) positioners support HART, Profibus, and Fieldbus protocols.
A: A Positioner regulates flow degrees. A Solenoid Valve only provides full Open or full Close control.
