190-SS-9-RTT-L-065-OF15 Flo-Tite 2-1/2 Stainless Steel 3 Piece Ball Valves, Econo-Groove 190

The Flo-Tite ECONO-GROOVE Series is designed as a split body, three-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 to end in the pipeline.Valve Features:Three Piece Body, Full Port Design1-1/2" to 6" SizesGrooved EndsBody: CF8M, 316SSRPTFE Seats or TFMPressure Rating: 1000 WOGTemperature Range: (-20?
