6.A butterfly valve is standard with the drain at the center point. This is the most versatile unit for use in the field whether emptying into tank, using a pump or gravity discharge. A ball valve is optional. It is used mostly in laboratory applications or where special application exists. The drain would then proceed at a 7 degree decline with the ball valve near the perimeter of the prover
