Atualmente, estamos usando GPS para localizar nossos ativos e, ao adicionar válvulas do sistema, fazemos o GPS no topo da caixa da válvula. Portanto, ao digitalizar os planos de registro, recebemos coordenadas tanto para a porca de operação quanto para o corpo da válvula. Estamos tentando encontrar a melhor forma de exibir isso no Pro. Abaixo está como estamos tentando exibir para que a válvula não fique flutuando, mas isso também causa problemas com nossos localizadores exibidos na última imagem quando eles localizam a área.<\/P>

I would definitely keep the valve body in line with the mains. When we have a butterfly valve where the nut is offset from center, we just show the GPS points for the nut and have it displayed. This way the topology stays intact and our locators/field crews can still locate the operator nut.

We are in process of converting to the UN and was not aware of the solution mentioned by @RobertKrisher but that seems like a good idea for us to consider when we make the transition.

Someone else suggested that symbology idea in our office as well and others couldn't let go that the gps point/ system valve was floating, then others wanted to represent the valve body and the operating nut as two different valves. So we are looking for the best temporary solution until we get to the UN that doesn't cause us alot more work later down the line.

I think our error would be must not have dangles, which could be an exception (like at the end of mains where we have blow offs). We do have the rule for valves not being covered by a line but would not give that error in this scenario if still touching the endpoint of a line.

So after thinking about it more, the topology isn't an issue really, but if you want to do tracing in the geometric network or UN in the future, I don't see how the trace would stop at that valve if it's position was closed. It would just bypass that valve since it is not in line. I think it would be worth it to get your valve points in a position that works with the network now, otherwise you will have a lot of work later on.

We had a similar dilemma years ago and another idea that came up that we didn't go with was making a symbol with maybe an arrow on it and rotating it to point on what side of the main the nut was on. If you don't have that many butterfly valves, that may be something to consider.

So does your topology give you an error of the valve not being covered by a line?

Thanks for this, we have a ways to go before we are ready for the UN, but we just setup topology rules to start cleaning up our data and this was something we have been discussing. So currently we record the system valve and operating nut in one field because probably 98% of our valves are gate valves and the nut is directly on top. Would we only use the operating nut feature when it's offset and would the connection between the two be visible without a actual line feature.

I would recommend having the operating nut be a separate feature in the GIS with its own symbology. It would also be good to show a connection from the operating nut to the valve it operates or have a relationship between the two. Here's an example of how this is handled in the utility network, where an operating nut has a connectivity association with a system valve.
