Ductile Iron Non-Rising Stem Resilient Seated Gate Valve For Fire Fighting Use
Product introduction:
Resilient seat sealed gate valve is a type of soft sealed gate valve, which is an industrial valve of elastic gate valve. Its opening and closing component is the gate, and the direction of the gate's movement is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled.
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.
