As the title suggests, I’m seeking advice from experts: what is the function of the button on the valve mechanism? What else is a two-speed electric valve? Are there materials I can use to learn?*
REM is an abbreviation for REMOTE, which means remote control； LOC is an abbreviation for LOCAL, which means on-site control ； STOP means to stop ； The arrow button on the right indicates that the valve is open; the top parallel lines with a diamond symbol indicate that the valve is fully open ； The arrow on the left indicates closing the valve, and a vertical line added in the middle of the bottom parallel lines shows that the valve is completely closed. O/S means valve on/off
This is a BIFFI electric actuator, similar to a ROTORK knob
Operating from a remote location involves internal control; the DCS is used to control the switches； Go to the site; it’s the on-site button switches and valves
Opening, closing, and stopping are buttons; knobs are used for local and remote stopping – local refers to on-site operation, while remote refers to off-site operation
