What is an NRS Gate Valve?

An NRS Gate Valve has a stem that remains stationary during operation, contrasting with a rising stem gate valve where the stem moves visibly up or down. The non-rising stem design keeps the stem enclosed within the valve body, making it perfect for areas with limited vertical space, such as underground water mains or fire protection systems.

How Does an NRS Gate Valve Work?

The NRS gate valve controls flow by moving a gate (or wedge) perpendicular to the medium's direction. In the fully open position, the gate is completely out of the flow path, resulting in minimal resistance. When closed, it lowers to form a tight seal, preventing any backflow. This unique design allows the valve to operate effectively even in restricted spaces without additional clearance.

Key Features of I-FLOW NRS Gate Valves

Compact Design: The enclosed, non-rising stem makes it ideal for limited-space installations, such as underground or enclosed systems.

Reliable Shutoff: A solid gate design provides a tight seal when closed, ensuring efficient flow control without leakage, making it suitable for diverse media like water, gas, and chemicals.

Durable Construction: Made from cast iron, ductile iron, or stainless steel, these valves withstand harsh conditions, ensuring dependable performance over the long term.

Corrosion Resistance: An epoxy-coated body and corrosion-resistant stem allow the valve to perform well in aggressive environments, including seawater, wastewater, or chemical applications.

Low Maintenance: The design minimizes wear on internal components, reducing maintenance needs. Additionally, the enclosed stem shields against debris and corrosion, supporting smooth, uninterrupted operation.

Cost-Effective Solution: With its durable design and minimal maintenance needs, the IFLOW NRS gate valve offers a reliable, cost-effective choice for industrial flow control.
