Features:

1. Floating seat, two-way opening and closing, reliable sealing and flexible opening and closing.

2. Both the gate and the gate are provided with precision guidance, and the sealing surface is sprayed with hard alloy and erosion resistance.

3. The body carrying capacity is high, the channel is straight-through, and when it is fully open, the flow resistance of the valve is similar to that of the gate of the gate, which is very small. The stem adopts compound packing, multiple sealing, making the seal reliable and the friction force is small.

4.When the valve is closed, the gate is moved down to the bottom, the inlet side is sealed by the pressure of the medium and the inlet is pushed towards the direction of the gate, forming a larger seal than pressure, thus forming the first seal. At the same time, the gate plate is pressed to the outlet seal seat to become a double seal.  

5. The sealing part is filled with grease fitting, which can be sealed when the valve is leaking.
