Technical Specifications
Installation precautions:DG100-DG250b type prefilling valve, when installing, the screw under port A should be installed last. When installing the screw here, first loosen the pressure plate screw, gently rotate the shell to a certain angle (for easy installation), and then install it. After the installation is completed, reset the shell and tighten the pressure plate screw again. Since there are seals on both the upper and lower parts of the shell, please be careful when turning to avoid damaging the seals.
