Flanged Resilient NRS Gate Valve is mainly used for fluid control in pipeline systems and has reliable switching functions. NRS stands for "Non-Rising Stem", which means that the valve stem remains unchanged during operation, and the valve disc is operated to open or close the flow of the pipeline by rotating the valve stem. The elastic seat seal design ensures that the valve has better sealing performance during the opening and closing process to prevent leakage. This valve is widely used in water supply, fire protection, water treatment and other systems. The flange connection makes it easier to install and maintain, and is suitable for application environments that require pressure resistance, strong durability and high sealing.

The resilient wedge design allows for smooth operation and easy maintenance, ensuring long-term reliability in various industrial settings.
The Flanged Resilient NRS Gate Valve boasts several key features that set it apart in the market. Firstly, its resilient wedge gate design provides a tight seal without the need for excessive torque, reducing the operating effort and extending the valve's lifespan. The valve is designed to handle a wide range of fluids, including water, steam, oil, and various corrosive substances, making it versatile for different industries. The flanged ends are engineered to meet ANSI B16.5 or equivalent standards, ensuring a secure and leak-proof connection. Additionally, the valve is available in various sizes and pressure classes to suit different pipeline requirements. The design also includes a rising stem, which provides visual indication of the valve's position, enhancing safety and operational efficiency.
The Flanged Resilient NRS Gate Valve is widely used in various industries where reliable shut-off and flow control are essential. Common applications include water treatment plants, oil refineries, chemical processing facilities, and power generation stations. The valve is particularly suitable for applications that require a high degree of shutoff integrity, such as isolating equipment for maintenance or controlling the flow in critical pipeline sections. Its robust construction and ability to handle a variety of fluids make it an ideal choice for both above-ground and underground piping systems. The valve's compatibility with flanged connections also simplifies installation and integration into existing systems, further enhancing its versatility and appeal.
1. What is the maximum pressure this valve can handle?
The Flanged Resilient NRS Gate Valve is available in various pressure classes, typically ranging from Class 125 to Class 2500. The maximum pressure it can handle depends on the specific class and size of the valve. It is essential to check the product specifications for the exact pressure rating that suits your application.
2. Can this valve be used for slurries or abrasive fluids?
While the resilient wedge design of the valve offers excellent sealing capabilities, the use of slurries or highly abrasive fluids is not recommended as they may cause premature wear of the sealing surfaces. For such applications, it is advisable to consider valves specifically designed for handling abrasive materials.
3. What is the expected lifespan of this valve?
The lifespan of the Flanged Resilient NRS Gate Valve can vary depending on several factors, including the operating conditions, fluid handled, and frequency of use. However, with proper maintenance and operation, this valve can offer many years of reliable service, often exceeding 10-15 years in many industrial applications. Regular inspections and timely maintenance are key to maximizing the valve's lifespan.
