The NRS (Non-Rising Stem) Gate Valve from I-FLOW is a durable and efficient solution for controlling the flow of various media in industrial piping systems. Known for its reliability and compact design, this valve is ideal for applications where vertical space is limited. Whether used in water supply systems, oil and gas pipelines, or chemical processing, the IFLOW NRS gate valve provides a dependable shutoff with minimal maintenance.
What is an NRS Gate Valve?
An NRS (Non-Rising Stem) Gate Valve is a type of gate valve where the stem remains fixed during operation, unlike a rising stem gate valve where the stem visibly moves up or down as the valve opens or closes. The non-rising design keeps the stem contained within the valve body, making it suitable for areas with height restrictions or underground applications such as water mains or fire protection systems.
How Does an NRS Gate Valve Work
The NRS gate valve operates by moving a gate (or wedge) perpendicular to the flow of the medium. When fully open, the gate is lifted entirely out of the flow path, offering minimal resistance and pressure drop. When closed, the gate is lowered to form a tight seal, preventing any media from passing through. Since the stem does not move upward, the valve can be operated in confined spaces without requiring extra clearance.
Key Features of I-FLOW NRS Gate Valves
Compact Design: The non-rising stem design makes this valve ideal for installations where space is limited, such as underground pipelines or enclosed systems.
Reliable Shutoff: The gate provides a solid, tight seal when closed, ensuring no leakage and optimal flow control. This makes the valve highly effective in handling various fluids, including water, gas, and chemicals.
Durable Construction: Manufactured from high-quality materials like cast iron, ductile iron, or stainless steel, I-FLOW NRS gate valves are designed to withstand harsh environments and provide long-term reliability.
Corrosion Resistance: With an epoxy-coated body and corrosion-resistant stem, these valves are suitable for applications exposed to corrosive elements such as seawater, wastewater, or chemically aggressive media.
Low Maintenance: The valve’s design minimizes wear and tear on the internal components, reducing the need for frequent maintenance. Additionally, the enclosed stem design protects against external debris and corrosion, ensuring smooth operation over time.
Cost-Effective Solution: With low maintenance requirements and a robust design, I-FLOW NRS gate valves offer a long-lasting, cost-effective solution for industrial flow control.
