Manual high-temperature circular plug valve
The circular gate valve is often used under the circular discharge port. The movement direction of the gate is perpendicular to the direction of the fluid. The circular gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
When the circular gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the medium pressure is used to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface. This is self-sealing. Most knife gate valves adopt forced sealing, that is, when the valve is closed, external force must be relied on to force the gate plate to the valve seat to ensure the sealing performance of the sealing surface.
