FREE-Valve’s Ceramic Slab Gate Valves are a sliding valve with a closed part as a parallel gate. The clamping force of the gate to the seat is controlled by the medium pressure acting on the floating gate or floating seat. The advantage of the flat gate valve is that the flow resistance is small and the flow resistance of the valve is similar to that of the short pipe. At the same time the gate valve is sliding on both seat surfaces, the flat gate valve can also be used for media with suspended particles, and the sealing surface of the flat gate valve can actually automatically position.
