The ball valve shall be metal to metal seated with flanged ends, drilled to the applicable ANSI B16.
1 standard Class 125. Valve shall have a clear unobstructed waterway, which will result in no significant head loss, when the valve is in the full open position. The valve shall be drop tight and meet or exceed the AWWA C507- (latest revision) inspection and testing standard. The valve shall be single seated for pump control and rated at 150 or 300 psi. The valve shall be as manufactured by Pratt. The valve shall consist of a body, ball and operating unit (actuator).
