Objective: I have a 12V switch and a rotating 12V valve. I want to be able to open the valve with the 12V switch, but once the valve fully opens, and bottoms out, to denergize power to the valve. The 12V switch, will stay in the 'on' position. Once I turn the 12V switch off, the same is done in reverse, and once the valve is fully closed, it is denergized.
I figure all the switch needs to recognize is when the valve bottoms out and surges the line. |

Need some kind of positioning on the valve. Ether micro switches that are physically pushed when the valve is fully open / closed or a magnetic pick-up. Run that through a NO / NC pair of relays and it will power down the valve when the switch is engaged. There is no way to access the valve to determine position. I am looking to be able to monitor position as fully open/closed based on power surge when the valve motor bottoms out. |

Atleast 93 to 02 probobly earlier than that. Maybe you could figure out how they do it. |

How about a solenoid valve? Thought of fuel/nitrous solenoid valves, but they are not meant to be energized for more than a min or two. I'm pretty sure you can get 12 volt solenoid valves that are continuous duty. Doing everything up in solenoids would mean alot of mass. All can be done with a 3/2 way valve the size of a pack of smokes. |

Get a click PLC with relay outputs and 2 analog inputs. Buy a 4-20mA current transducer. Use the current transducer to detect the change in current draw from the stalled motor. You're on the right track, but isn't there a relay, or even a 12V switch out there that all ready does that in one compact package. I really think that there is a simple solution to this, and don't need to go as far as getting a PLC. |

Your going to need rslogix 5000 and a Plc. Run control and power lines. Screw limit switches they wear out. Lets do prox switches instead. Wait, what was the budget? $50 Time the cycle time and use a programmable relay. There is an option. Do you have anything in mind, as the majority of what I'm coming across is far too big. Looking for something that is the size of a automotive relay. |

What kind of valve are we talking about here, ball or gate? ETA, IOW, does it need 90 degrees of travel, or several revolutions? WVO Valve From what the sales associate informed me (I believe she is 99% misinformed) is that the valve continually rotates, and is not just a simple 90 degree. |

If you don't mind me asking, what are you using it for?
Would something like this work? http://www.karlssonrobotics.com/cart/12v-solenoid-valve-34/?gclid=CLub19vx37cCFRDl7AodNWsAnA |

What about an OEM type solution?
I assume your EFI with that pressure but are you rubber lines or AN fittings? Example: http://compare.ebay.com/like/230942561470?var=lv<yp=AllFixedPriceItemTypes&var=sbar# |

What will trigger this WOT condition? |

Thanks to everyone for their help an options.
I'm rolling the dice and taking SuperJanitor opinion that it is a constant duty solenoid, and will confirm tomorrow. If all else fails you'll hear from me tomorrow. To keep with the GD theme: F U AROCK... with a pine cone! |
