Performance Analysis of Pilot Controlled Check Valve under Varying Pressures

This chart illustrates the performance of a pilot controlled check valve with varying input pressure settings. The x-axis represents the pressure in Bar, while the y-axis displays the corresponding flow rate in liters per minute (L/min). As observed, there is a significant correlation between the pressure exerted on the valve and the resultant flow rate. At zero pressure, the flow rate remains at zero, indicating that the valve remains closed. However, as the pressure increases to 25 bar, the flow rate reaches a maximum of 50 L/min. This behavior is typical for check valves, which are designed to permit flow in one direction while preventing backflow. Understanding this relationship is critical for engineers and designers when selecting valves for specific applications, ensuring that they operate efficiently under the expected pressure ranges. Such analysis helps optimize fluid systems, maximize performance, and enhance safety in industrial and hydraulic applications.
