A valve body having a cylindrical flow passage therethrough is formed with end sections, each of which has a surface adapted for sealing engagement with a face of the pipe flanges, and a clapper being mounted for pivoting between a closed position completely blocking the valve body flow passage and an open position withdrawn from the flow passage but within the valve body.
