Brass Screwed Steam Non-Return Valve
Steam non-return valve (NRV), otherwise known as stop or check valve, allow steam flow in one direction, and automatically prevent backflow. In other words, they prevent steam from flowing back to the main header of the boiler, or back to a boiler that has failed or is off-line.
Description
A Brass Screwed Steam Non-Return Valve is a type of valve designed to prevent backflow of steam in a pipeline. It features a brass body, screwed connections, and a non-return valve design. The primary function of a Brass Screwed Steam Non-Return Valve is to allow steam to flow in one direction while preventing it from flowing in the opposite direction. This ensures that steam flows only in the intended direction, preventing backflow and potential damage to equipment.
Characteristics
1. Brass body: The valve’s body is made from brass, providing excellent corrosion resistance and durability.
2. Screwed connections: The valve features screwed connections, making it easy to install and remove from pipelines.
3. Non-return valve design: The valve’s non-return design ensures that steam flows only in one direction, preventing backflow.
4. High-temperature resistance: The valve is designed to withstand high temperatures, making it suitable for use in steam systems.
5. Low maintenance: The valve requires minimal maintenance, as it has few moving parts and is easy to clean.
Applications
1. Steam systems: Brass Screwed Steam Non-Return Valves are commonly used in steam systems for heating, power generation, and process applications.
2. Boiler systems: The valve is used in boiler systems to prevent backflow of steam and ensure safe operation.
3. Process industries: The valve is used in various process industries, including chemical processing, oil refining, and food processing.
4. Power plants: The valve is used in power plants to control steam flow and prevent backflow.
Types
1. Standard Brass Screwed Steam Non-Return Valve: The standard valve features a brass body, screwed connections, and a non-return valve design.
2. High-Pressure Brass Screwed Steam Non-Return Valve: The high-pressure valve is designed for use in applications where high pressures are present.
3. Low-Pressure Brass Screwed Steam Non-Return Valve: The low-pressure valve is designed for use in applications where low pressures are present.
4. Customized Brass Screwed Steam Non-Return Valve: The valve can be customized to meet specific application requirements, including specialized materials, sizes, and configurations.
