Thank you folks for the inputs!
The input summary for U/G valve:
* use 'vertical culvert','well' or 'valve box' to contain and keep valves from the dirt and water.
* use AWWA, rubber-lined valves.
* stroke U/G valves regularly to ensure they are operable.
Thanks again!

We are petrochemical operator, with little experience in underground buried valves for utility service--firewater, cooling water, potable water, process effluents, sewer, .... We found many of the exisitng U/G valves seized and inoperable. I need to spec out new replacement valves. Please...
