Masoneilan SVI II AP Digital Valve Positioner Masoneilan 12400 Series Digital Level Transmitter Pneumatic Level Controllers

The SVI II AP is advanced performance digital positioner with HART protocol. It controls pneumatic actuators using a two-wire 4-20mA signal and provides local display/pushbuttons even in hazardous areas. It's known for non-contact sensing, quick commissioning, and upgradable diagnostics – a common choice for reliable valve positioning in process industries.
