3.2 The test pressure liquid should be the same as the working liquid, and the pressure should be maintained for 10 minutes. There should be no leakage and pressure reduction at the seals and ports. 3.3 The valve body is not allowed to be connected to the valve body, only the valve differential is used. 4 Marking example
