Using a regulator on the secondary side When mounting a regulator on the secondary side (A port side), use a residual pressure relief regulator (AR2550 to 4050) or a check type regulator (AR2560 to 6060). With a standard regulator (AR1000 to 6000), the secondary side pressure may not be released when this valve is exhausted. 5.
