The Anvil Stainless Figure 469 Ball Valve is a Teflon seated full port ball made of stainless steel and the cast equivalent to 316 Stainless Steel, CF8M. The full port, commonly called full bore, ball valve creates an unrestricted flow reducing head loss through the valve. The flow can enter the valve from either direction which allows the valve to be oriented in different positions in tight spaces. The valve is a 1/4 turn open/close with a latch lock in both the full open and closed positions. The inline direction of the handle when the valve is open lets you see whether the valve is opened or closed. The lock latch has a lock-out feature to pad lock the valve in the open or closed position.
