A full bore gate valve maintains it’s diameter which allows fluid to flow through the entire diameter of the opening. The gate in the valve can be fully or partially open which provides some control over the flow rate. Compared to a gate valve that is not a full bore type, the flow is restricted to a smaller passage as it flows through the valve.
This brass gate valve has a nominale diameter of 65mm & is a full bore gate valve.
