Class 4500 LB Check Valve
A Class 4500 LB Check Valve is a specific type of check valve designed to operate within a pressure rating of Class 4500 LB (approximately PN750). It functions as a one-way valve that allows fluid to flow in only one direction, opening in response to fluid movement and pressure and closing to prevent backflow. These valves are crucial components in plumbing systems, as well as in various industrial applications, where they safeguard upstream equipment such as pumps and compressors by preventing the reversal of fluid flow, thus ensuring the efficient and safe operation of the system.
