Check valves are essentially unidirectional valves that prevent the backflow of liquid in a system. They are primarily used to protect equipment like compressors and pumps and hence, are available in various designs and cast and forged bodies. API 6D Swing Check Valves are a special specification of check valves that are used in pipelines. Some other ones include the following:
• API 602: Forged steel
• API 603: Stainless steel
• ASME B16.25: Buttweld connections
• ASME B16.34: Temperature and pressure ratings
• BS 1868: standard type, carbon and allow type
Applications of swing check valves
The API 6D swing check valves serve as a simple solution in various industries, some of which include the following:
• Power plants: silent check valves are frequently used in high-pressure fluid control applications like cooling towers.
• Horizontal water lines: Swing check valves are ideal for consistent-pressure high-volume fluid applications like water pumping and wastewater management
• Petroleum refineries: Oil and gas refineries use a special variant called non-slam check valves to mitigate the pressure wave created by a slamming valve.
• Natural gas transmission: Swing check valves prevent the improper flow of gas, which could result in dangerous leaks or fires. They are highly used in commercial and residential gas meters, compressors, etc.
API 6D swing check valves are low maintenance equipment and are the preferred choice for various horizontal piping applications since they do not require an external power source to work. You can contact a professional valve manufacturing company to find out which one best suits your requirements.
