sscase Posted January 16, 2013 Share Posted January 16, 2013 Has anyone used a 2-way normally open solenoid valve for main water shut off? Looking to buy a 2-way normally open solenoid valve and wire it to a I/O extender that has water sensors.Thanks in advance! Link to comment Share on other sites More sharing options...
adam333 Posted January 16, 2013 Share Posted January 16, 2013 are you saying for your main water supply to your house? Link to comment Share on other sites More sharing options...

Cyknight Posted January 16, 2013 Share Posted January 16, 2013 I have but as they've always been installed by a plumbing company I can't help you on brands etc. Works just fine though.The one's we've done have all been 120v though, so we've used a C4 switch on them.

Then you energize or de-energize the solenoid valve via the C4 switch, so did you even need the I/O extender? Thanks! Link to comment Share on other sites More sharing options...
avittech Posted January 16, 2013 Share Posted January 16, 2013 We use a KZvalve which runs on 12v - 24v dc or ac and has contacts to open / close with status notifications confirming valve open or closed Link to comment Share on other sites More sharing options...

Thanks!For these it's normally open so we turn ON the switch to CLOSE the valve - no i/o needed. Link to comment Share on other sites More sharing options...

Want to underscore the "as I understand it" as I wasn't directly involved in the "selection" process.As most valves are single contact only (normally open, you close (energize) the circuit to close the valve), it's ALWAYS discreet, so additional contact sensors aren't really required for a C4 system - just program notifications directly off of the relay state.
