Excuse me, expert – what does this gauge symbol mean? What is this S? Novices don’t understand this aspect

S: Solenoid valve; ROV: Remote Operate Valve; IA: Instrument Air; ZSC: Valve position feedback; XCV: Valve actuation command. Check the P&ID legend! ! !

Expert, is this the valve that can be switched on and off both via remote control and manually on-site?
