I-FLOW NRS Gate Valve Overview

Time: 28-October 2024 | Source: I-FLOW| Share

The I-FLOW NRS Gate Valve is expertly crafted to offer compact, reliable, and resilient flow control across various industries. Featuring a non-rising stem design, corrosion-resistant materials, and a dependable shutoff function, this valve is designed to boost system efficiency and safeguard critical operations. Its enclosed stem makes it ideal for applications with vertical space constraints, such as underground pipelines, where it consistently delivers long-lasting, cost-effective performance.
What is an NRS Gate Valve?
An NRS (Non-Rising Stem) Gate Valve is distinct because its stem does not extend outward during operation, unlike a rising stem valve. Instead, the stem remains stationary within the valve body, making it ideal for installations with height restrictions or confined spaces like water mains and underground fire protection systems.
How Does an NRS Gate Valve Work?
The NRS gate valve opens and closes by moving a gate (or wedge) perpendicular to the flow direction. In the open position, the gate is fully retracted, allowing unrestricted flow and minimizing pressure drop. When closed, the gate seals tightly, preventing any backflow. This design allows the valve to be operated effectively without additional vertical clearance.
Key Benefits of I-FLOW NRS Gate Valves
Space-Saving Design: The compact, non-rising stem is ideal for installations in tight spaces or below ground, where vertical space is limited.
Dependable Shutoff: The gate’s design ensures a secure, tight seal when closed, ensuring no leakage and precise flow control for diverse media, including water, gas, and chemicals.
Built for Tough Environments: Constructed from robust materials like cast iron, ductile iron, or stainless steel, I-FLOW NRS gate valves are built for longevity in demanding conditions.
Superior Corrosion Resistance: An epoxy-coated body and corrosion-resistant stem make the valve suitable for harsh environments, from seawater exposure to chemically aggressive applications.
Low Maintenance Needs: The enclosed design minimizes internal wear, reducing the frequency of maintenance. The stem's protective enclosure also guards against external contaminants, promoting smooth, consistent operation.
Cost-Efficiency: With its resilient build and low maintenance requirements, the I-FLOW NRS gate valve offers a durable and cost-effective solution for industrial flow control.

What Are The Four Types of Valve Actuators

Every valve needs something to move it. That “something” is the actuator. It supplies the force that opens or closes the valve so fluids can flow when you want and stop when you don’t. Some actuators are simple. Others are designed for speed, power, or precision. In general, there are four main types: manual, pneumatic, hydraulic, and electric.
