DM51-BZ-TTT-020 Flo-Tite 3/4 Brass-Plated Ball Threaded Ball Valves, Direct Mount DM51

The Flo-Tite DM51 / DM52is designed as a split body, two-piece construction, to allow ease of access for maintenance of the valve ball and seat without special tools. This line of valves utilizes the "free floating" ball principle. The ball is not fixed but is free to move with the line pressure. As a result, these valves are capable of tight shut-off with the flow in either direction or dead-ended, regardless of the position of the valve in the line. The downstream seat, which is opposite the pressurized side, of a closed valve, must carry the load exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase useful seat life by turning the valve end-for-end in the pipeline.Features:Stainless - Full Port Low Torque Design1000 WOG - 150 WSP Pressure:Temperature up to 370°F1/4" thru 4" size range
