Characteristics
The gate valve's key operating component is the gate plate, which executes a linear reciprocating motion perpendicular to the direction of fluid flow. A defining operational characteristic of this valve type is that it is engineered exclusively for full-open and full-close functions, this design ensures unobstructed flow passage when fully open, and reliable shut-off performance when fully closed.
The valve achieves its exceptional sealing performance through an integral rubber-coated gate plate.
Advantages
Long service life: The adhesive strength between the valve plate rubber and the cast iron skeleton is high, and the coating thickness is higher than the national standard. Advanced injection molding technology is used, and the surface of the gate plate is smooth and defect free, with uniform rubber thickness and good elasticity. At the same time, the valve body, valve cover, and valve plate frame are precision cast with ductile iron, which has good density, can withstand high pressure, and is not easily broken, extending the service life of the valve.
Not easy to accumulate debris: The bottom adopts a flat bottom design, similar to the pipeline, which is not easy to cause debris accumulation and allows the liquid to flow smoothly, especially suitable for fluid media containing impurities.
Lightweight: The valve body is made of ductile iron casting, which reduces the weight by 20%–30% compared to traditional gate valves, making it easy to install and maintain.
Packing
Standard export wooden case packaging
Application Scenarios
The resilient-seated gate valve is a widely utilized shut-off and isolation device across fluid handling pipelines in municipal, industrial, and building services sectors.
Frequently Asked Questions
Q What is a resilient seat gate valve and how does it work?
A A resilient seat gate valve uses a rubber-coated gate plate that moves linearly perpendicular to the fluid flow direction. It is designed exclusively for full-open and full-close operations, providing unobstructed flow when fully open and reliable shut-off when fully closed.
Q What standard does this gate valve comply with?
A This resilient seat gate valve complies with the DIN F5 standard, ensuring it meets internationally recognized quality and dimensional requirements for industrial and municipal pipeline applications.
Q What is the operating temperature range of this valve?
A The valve is rated for operating temperatures between -20°C and 120°C, making it suitable for a wide range of water supply, drainage, and industrial fluid applications.
Q Why is ductile iron used for the valve body and gate plate frame?
A Ductile iron offers excellent density, high-pressure resistance, and reduced brittleness compared to traditional cast iron. It also reduces the overall valve weight by 20%–30%, making installation and maintenance easier while extending service life.
Q Is this valve suitable for fluids containing impurities or debris?
A Yes. The flat bottom design of the valve body is aligned with the pipeline profile, which prevents debris accumulation and allows smooth fluid flow, making it especially suitable for media containing suspended particles or impurities.
Q What are the typical application sectors for this resilient seat gate valve?
A This valve is widely used as a shut-off and isolation device in municipal water supply and drainage systems, industrial fluid pipelines, and building services infrastructure, thanks to its zero-leakage sealing and bidirectional sealing capability.
