Ayvaz NRS Non-Rising Stem Valve DIN Flanged Principle
The Ayvaz NRS Non-Rising Stem Valve with DIN Flange is a valve frequently used in fire installation systems, providing control and shut-off functions in underground pipelines. This non-rising stem valve features a mechanism that facilitates control, particularly in large-diameter pipes. As one of the most critical components of fire systems, the valve possesses the structural features required for safe and efficient operation.
Ayvaz NRS Non-Rising Stem Valve DIN Flanged Operating Mechanism
The NRS Non-Rising Stem Valve is based on the principle that the stem (stem) does not move up or down when the valve is opened or closed. This feature makes it ideal for use in underground applications or in confined spaces. When the valve is opened or closed, the stem within the body transfers the rotary motion to the disc. The disc is a flat disc that controls the flow of water through the pipeline. As the stem rotates, the disc moves along the horizontal axis, opening or closing the flow of water.
Ayvaz NRS Non-Rising Stem Valve DIN Flanged Post Indicator
Due to its non-rising stem design, the NRS valve is typically used with a post indicator. The post indicator is located on the valve body and includes an indicator that indicates whether the valve is open or closed. This feature allows for quick and easy checking of valve status, especially when the valve is underground. The indicator clearly indicates the open or closed position, enabling rapid intervention in emergency situations.
Ayvaz NRS Non-Rising Stem Valve with DIN Flange Application Areas
These valves are designed for use in buried pipelines, particularly in outdoor locations prone to freezing. They are effectively used as control and shut-off valves in fire systems, as well as in main lines and hydrant systems.
The Ayvaz NRS Non-Rising Stem Valve with DIN Flange is an essential component of fire safety systems. ORFA Industrial Products Industry and Trade Inc. sells this product, providing its customers with high standards of safety and performance. By choosing this reliable valve for your fire safety, you can ensure trouble-free operation of your system for many years to come.
