4 in. 2-Piece 316 Stainless Steel Full Port Ball Valve, 1000 PSI (949180)
4 in. 2-Piece 316 Stainless Steel Full Port Ball Valve, 1000 PSI (949180)
The 4 in. 2-Piece 316 Stainless Steel Full Port Ball Valve (#949180) is a 1000 PSI WOG full-port valve for corrosive, high-pressure, and high-temperature fluid service where brass or PVC won't hold up. 316 stainless body and ball, PTFE seats, and a locking quarter-turn handle make it a standard choice in chemical processing, oil & gas, steam, and food-grade lines. At 4-inch full port, it delivers maximum flow with minimal pressure drop in large-bore process lines.
