Gate Valve Manufacturer
When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves use forced sealing, that is, when the valve is closed, the gate must be forced to press against the valve seat by external force to ensure the tightness of the sealing surface.

The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium. It saves effort to open and close. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure. The shape is simple, the length of the structure is short, the manufacturing process is good, and the scope of application is wide.
According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve
The working principle is different. The shut-off valve has a rising stem type, and the hand wheel rotates and rises along with the stem. For the gate valve, the hand wheel rotates and the valve stem moves upward. The flow rate is different, the gate valve is required to be fully opened, the stop valve is not. The gate valve has no requirements for the import and export direction, and the globe valve has a specified inlet and outlet!
