Electric valve question

[MarkMCM]

LIvestock watering system with well pumping to a storage tank and a line pump from the storage to the field.

Storage tank is on high point of property. Line pump is 40 feet lower than storage.

I have a float valve to shut off the line pump when tank gets to half. However, if we have a failure in the field, the pump shuts off but the tank will gravity flow to empty. Big problem.

I can connect an electric valve to the relay operating the line pump. It is 1 1/2" line.

I found this in an old valveman response http://www.sprinklerwarehouse.com/Toro-NPT-Irrigation-Valve-Scrubber-p/p220s-26-08.htm

However, it is 24 volt. Everything in the pump house is 110 or 220. Do I use this with a transformer or are there better options?

I need 15 gpm flow that can shut off against 40 feet of head.

Thanks for your help.

I don't really understand what you are trying to do, but 110 or 230 volt to 24V transformers are common. And 24V is safer for solenoid valves.

If we have a line failure in the field, the line pump will shut off when the storage tank drops to half. However, the water will continue to gravity feed the leak at the failure until the storage is drained.

I need a valve to stop the gravity feed when the line pump shuts off due to low level.

Your cycle stop and cycle sensor are working great in our system. Thanks.

Why not a flapper style check valve?
