What is the cracking pressure for each AK series check valve?

The cracking pressure of each AK series is as follows. AK series: 0.02 MPa, AKB series: 0.005 MPa, and AKH series: 0.005 MPa.
The cracking pressure is the pressure (differential pressure between the inlet and outlet) at which a certain flow rate can be observed when the valve begins to open.
