• When the valve is opening and closing, the sealing surface of the valve body always keeps in contact with the sealing surface of the gate disc to prevent impurities from adhering to the sealing surface and maintain a tight sealing effect.

• Double directional hard seal structure, make sealing performance excellent.

• The valve stem with a large lead thread transmission to achieve quick opening and closing.

• Using high-performance fillers with minimal frictional resistance, automatic lubrication, and resistance to coal gas and various corrosive gases.

• A spray nozzle designed on the valve body for spraying and sweeping the dirt accumulated in the valve cavity and sealing parts.
