  • Overview of Wedge Gate Valve

    The disc of the wedge gate valve is wedge-shaped, and the purpose of using the wedge shape is to increase the auxiliary sealing load, so that the metal-sealed wedge gate valve can not only ensure high medium pressure sealing, but also low medium pressure. In this way, a metal-sealed wedge gate valve can achieve a higher potential level of sealing than a common metal-sealed parallel gate valve.

  • The working principle of the check valve

    Under the action of the fluid pressure flowing in one direction, the valve disc opens, when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve disc act on the valve seat, thereby cutting off the flow. Among them, the swing check valve belongs to this
