Valve [2], the more common as a lower-level valve. Gate valve [3] Advantages 1, fluid resistance. 2, opening and closing the external force is small. 3, the flow of the medium is not restricted. 4, fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve. 5, the relatively simple shape, the casting process. , The shortcomings of the valve [4], dimensions and open height. Space required for installation. 2, the opening and closing process, the sealing surface between the relative friction, easy to cause abrasions. 3, the gate valve [5] generally have two sealing surface, add some difficulty to processing, grinding and repair.
