I am looking for the proper type of valve to install to bleed pressure off water mains when they have to be taken down for maintenance. The specific instance is a 72" main with a 6" tee and valve piped to open air to release water to drop pressure to zero. The problem I see is with a large volume of water (big pipe at 100psi) moving past a valve as it's opened, it's likely to have some damage to the gate. I see that RW gate valves specifically say 'throttling' is not an intended use. Any suggestions on a readily available municipal water works valve for this application?
