Van cổng ngồi đàn hồi NRS

The NRS resilient seated gate valve is widely used in water supply and distribution systems due to its non-rising stem (NRS) design, which is ideal for installations with limited vertical space. The resilient seat, typically made of rubber or elastomer, ensures tight sealing and bubble-tight shutoff, even in low-pressure conditions. Its corrosion-resistant components and full-bore passage reduce pressure loss and prevent debris buildup, making it a reliable choice for clean and wastewater applications. The NRS design also keeps the stem protected from external elements, reducing wear and extending valve life with minimal maintenance. It's easy to operate manually or with actuators and is especially well-suited for underground or confined-space use. Overall, it offers a cost-effective, durable, and efficient solution for controlling flow in municipal, irrigation, and industrial pipeline systems.
