Where are flanged gate valves with concealed stems used?
The flanged gate valve with a concealed stem is a type of valve that combines a concealed stem design (where the stem is located inside the valve body) with a flanged connection. Due to its compact structure and ease of installation and maintenance, it is widely used in various piping systems. Its main application areas include:
**Urban Infrastructure:** In urban water supply and drainage systems, it is used to control the flow and pressure of water supply networks to ensure stable water supply, and in drainage systems, it regulates the discharge of wastewater to prevent backflow and leakage.
**Industrial Sector:** In the piping systems of industries such as petrochemicals, metallurgy, water treatment, and thermal power generation, it serves as a device to open and close media pathways (such as oil, steam, or chemical raw materials), thereby ensuring the stability and safety of the production process.
**Construction Industry:** In the internal water supply, drainage, and fire protection systems of various buildings, such as residences, shopping malls, hospitals, and schools, it is used to control water distribution and provide local isolation during maintenance. Its soft-sealing design also helps to reduce noise generated by water flow.
**Water Resources and Environmental Protection:** In agricultural irrigation systems, it regulates the distribution of irrigation water to improve water resource efficiency; in wastewater treatment and waste gas emission systems, it controls fluid flow to ensure compliance with environmental regulations.
**Other Applications:** Additionally, it is widely used in numerous other fields that require fluid control, such as the food and pharmaceutical industries, light textiles, power generation, shipbuilding, and energy systems.
In summary, the flanged gate valve with a concealed stem is ideal for a wide range of industrial and domestic piping systems that require reliable shut-off functionality and specific spatial considerations.
