In the world of fluid management, resilient seated gate valves play a crucial role in ensuring smooth, reliable, and leak-free operation. Among various valve types, the double flanged resilient seated gate valve has become a preferred choice for water, wastewater, and industrial systems worldwide. Its robust design, superior sealing, and long service life make it an essential component for consistent flow control.
What Are Double Flanged Resilient Seated Gate Valves?
A double flanged resilient seated gate valve is designed with flanges on both ends, making installation between pipes easy and secure. The “resilient seated” part refers to the soft, rubber-like coating on the wedge or gate, which ensures a tight seal against water pressure even under challenging conditions.
These valves are mainly used in pipelines to start or stop the flow of fluid, not for throttling. When open, the gate is lifted fully, allowing unobstructed flow. When closed, it creates a 100% watertight seal, preventing leakage and backflow.
Key Features of Double Flanged Resilient Seated Gate Valves
-
Durable Construction:
Made from ductile iron (DI) or cast iron (CI) with epoxy coating for corrosion resistance. The body design ensures long-lasting performance in harsh environments. -
Resilient Sealing:
The EPDM or NBR rubber lining on the wedge provides a bubble-tight shut-off and reduces wear and tear compared to metal-seated designs. -
Double Flanged Ends:
Allows for easy installation and removal in pipeline systems, ensuring a strong and leak-proof connection. -
Low Operating Torque:
Smooth handwheel or gear-operated mechanisms ensure effortless opening and closing, even in high-pressure systems. -
Non-Rising Stem Design (Optional):
Ideal for underground or limited-space applications, this design prevents stem movement outside the valve body. -
Pressure and Temperature Ratings:
Typically suitable for PN10, PN16, or PN20 pressure classes and temperature ranges from -10°C to 80°C, depending on material selection.
Advantages of Using Double Flanged Resilient Seated Gate Valves
1. 100% Leak-Proof Operation
The soft-seated design ensures complete sealing, reducing water loss and preventing contamination. This makes the valve ideal for potable water and wastewater treatment systems.
2. Long Service Life
With a high-quality ductile iron body and corrosion-resistant coatings, these valves deliver extended performance, even in challenging industrial environments.
3. Easy Maintenance
The bolted bonnet and flanged ends allow for quick disassembly, making inspection and maintenance simple.
4. Cost-Effective
Their durability and low maintenance requirements make them a cost-efficient choice over the long term.
5. Versatile Applications
From municipal water supply networks to fire protection, irrigation, and industrial systems—these valves can handle various flow conditions effectively.
Applications of Double Flanged Resilient Seated Gate Valves
These valves are highly versatile and find applications in several sectors:
-
Water supply and distribution systems
-
Wastewater treatment plants
-
Irrigation and agricultural pipelines
-
Fire protection networks
-
Industrial fluid systems
-
HVAC and cooling systems
Their reliable sealing and robust design make them indispensable for ensuring safe, controlled fluid flow across different industries.
Why Choose Double Flanged Design?
The double flanged design provides excellent support to the valve body and maintains alignment with the pipeline. It minimizes stress on joints and prevents leakage, even under high-pressure conditions. This design also simplifies installation, especially in systems where stability and strength are critical.
In addition, double flanged valves are easier to replace or maintain, as they can be easily removed without disturbing the pipeline alignment.
