How to adjust the outlet size of secondary protection solenoid valve

You can install a proportional valve in front of the machine to adjust it.

Solenoid valve can't control the air pressure and size, it only controls the forward or backward movement of the cylinder, so it needs to be adjusted by proportional valve.

Double shielded welding (full name carbon dioxide gas shielded welding) process is suitable for welding various large steel structures of low carbon steel and low alloy high strength steel, and the electromagnetic valve can control the front and rear positions of the cylinder.
