3 in. 3-Piece 316 Stainless Steel Ball Valve
3 in. 3-Piece 316 Stainless Steel Ball Valve
The 3 in. 3-Piece 316 Stainless Steel Ball Valve (#949279) is a 1000 PSI WOG valve for water, oil, and gas service in harsh, corrosive environments. Its 3-piece body unbolts so the seats and seals can be cleaned or replaced in-line — without removing the valve from the pipe — making it the go-to choice for maintenance-intensive and sanitary-adjacent systems. 316 stainless construction, PTFE seats, and a locking quarter-turn handle.
