The Check valve is actuated when the pressure difference between the inlet and the outlet reaches the range of cracking pressure. Reseal Pressure The downstream pressure at which the check valve closes bubble-tight. The Check valves that have higher cracking pressure can be resealed to bubble-tight by the spring force. The reseal pressure is the pressure at the same flow direction, but lower then the cracking pressure. Back Pressure The Check valves that have cracking pressure psig(.bar) and lower may not be able to return to the bubble-tight seal. This may require back pressure to press the seal to form a bubble-tight contact in addition to the spring force. Note -When the check valve is not actuated for a period of time, it may require initially crack at higher than the above cracking pressure ranges. -Check valves are designed for directional flow control only. Therefore ANSUN check valves should never be used as code Safety relief devices.
