Am I overthinking this or is it simply a check valve? Water only flows from the lower 510 hgl zone to the higher 600 hgl zone when the 600 hgl zone drops pressure significantly during a fire flow event?
Just noticed I didn't fully respond to hsbcn. The pressure we are dealing with is domestic water distribution, so between 20psi and 120 psi depending on elevation.
Okay, thanks for all the replies.
510 and 600 are referring to the ft in head, yes.
So as JohnGP says, that's the functionality I'm looking for. Basically the 510 ft of average head zone can provide some water to the 610 average head zone during a fire flow event in the 610 zone when the 610...
itascot: I'm not familiar with SRV? PSV is most likely what I want/mean. What I'm hoping is someone can read what I'm trying to accomplish and tell more more or less the physical device that matches up with my WaterCAD model's behavior. As in, the valve in essence isolates the 600 zone...
Civil engineer here modeling in WaterCAD. I have a 510 Zone HGL system interfacing with a 600 HGL Zone system. I currently have a PRV to separate the systems. Line size is 16". In most cases the systems operate independently and there is no flow across PRV. However if I run a fireflow...
