Frequently Asked Questions (FAQ)

What is a NRS Knife Gate Valve?

A NRS (Non-Rising Stem) Knife Gate Valve is a type of valve that has a flat gate with a sharpened edge for cutting through thick fluids or solids. It is operated with a rotating stem but does not have a rising function like some other valves.

What materials are NRS Knife Gate Valves made of?

NRS Knife Gate Valves can be made of various materials depending on the application requirements, such as cast iron, stainless steel, carbon steel, or plastic. The article mentions that some valves are coated with epoxy or rubber to enhance their corrosion resistance.

What are the benefits of using NRS Knife Gate Valves?

Some benefits of NRS Knife Gate Valves include their ability to handle high pressures, abrasive slurries, viscous fluids, and even dry materials. They are also compact, easy to install, and require little maintenance. Moreover, they can provide a tight seal to prevent leakage or contamination.

What industries use NRS Knife Gate Valves?

NRS Knife Gate Valves are commonly used in industries such as mining, pulp and paper, wastewater treatment, power generation, and chemical processing. They can be applied in various applications such as dewatering, tank isolation, powder handling, and pipeline control.
