Highlight: Bevel Gear Flanged Gate Valve
Product introduction:
The gate plate of a gate valve has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape, and the wedge angle varies with the valve parameters. The gate plate of a wedge gate valve can be made into a whole, called a steel gate plate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.
Soft sealed gate valve is a replacement product of traditional gate valve, which utilizes the compensation effect of elastic gate plate to produce slight deformation and achieve good sealing effect. This valve has significant advantages such as lightweight switch, reliable sealing, good elastic memory, and long service life. It can be widely used in fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, etc.

Product features:
1.High quality rubber is adopted for the internal and external encapsulation of valve, and the connection between rubber and valve is reliable and not easy to fall off;
2.As three "O"-shaped rings are designed on valve rod, the friction resistance of switch can be reduced and water leakage can be decreased significantly;
3.Corrosion resistance.
