TOP ENTRY

The ball is mounted on a trunnion which supports the pressure load. The seats are spring energized to allow tightness at low pressure, while the seats are energized by the pressure itself at high pressure. Body construction is one piece, made by forging or casting. The ball is inserted from the top and it’s possible to disassembly the valve in line.
