                  [Valve features]

                  1, The valve is to rely on the stem pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the flow of media. It belongs to forced seal type valve.

                  2, Valve medium flow "low prices" and "high low" in two, only the medium one-way flow direction when installing.

                  3, When the valve is opened, the opening height of the valve to reach the nominal diameter of the valve 25% to 30%, the flow has reached the maximum, that is, the cut-off valve has reached the fully open position.

                  4, The cut-off valve structure is simpler than the gate valve, manufacturing and maintenance are more convenient.

                  5, The sealing surface is not easy to wear and scrape, sealing good, open and close, the valve and the valve body sealing surface between the relative sliding, and thus grinding.
