High Performance Lined Ball Valve - Floating Ball Valve – Nortech
What’s floating ball valve? A Floating Ball Valve uses a rotating ball and a stem that provide on/off flow control. The floating ball valve utilize natural line pressure to press and seal the ball against the downstream seat. The line pressure is exposed to a greater surface area – the entire upstream face of the ball, which is an area equal to the actual pipe size. A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts t... -
