Swing Cast Steel Check Valve For Sale A cast steel check valve serves the purpose of maintaining the flow of fluid in a consistent direction within a pipe. These valves find application in specific industries such as water distribution, the oil sector, petrochemical plants, and gas and diesel circuits. By allowing fluid to flow in one direction while preventing backflow, cast steel check valves ensure efficient operation and help maintain the integrity of the piping system in various industrial environments.
Check Valve Industrial Check Valve for Sale Trust BST Valves to provide you with high quality swing check valves and a variety of different check valves for all your backflow prevention needs. What is a check valve? Check valves are used to ensure that gases and liquids flow in only one direction. They essentially prevent the process flow from flowing back, thus forcing the valve to close. Correct flow pressure forces the check valve open, while reverse flow causes the valve to close. Flow check valves open at the designed minimum flow or cracking pressure so that the valve can begin operation. Check valves protect the system from pressure fluctuations that can cause damage to pumps and pipes and help operate efficiently. Check valves are required to stop backflow and protect rotating equipment and machinery from sudden backflow surges that may occur. BST Valves is a manufacturer specializing in check valves, offering industrial check valves in a variety of configurations and materials, including Cast Steel Check Valves and Stainless Steel Check Valves. Our check valves are industry proven for use in a wide range of applications from oil and gas to pulp and paper.
