Where is the safety return valve used?

When the outlet pressure of the liquefied petroleum gas pump is too high, it will cause the liquefied petroleum gas to return automatically. At this time, a safety return valve needs to be installed.

In the system of filling steel cylinders with pumps, due to frequent changes in the filling volume, especially when the filling is suddenly stopped in a short period of time, vibrations and other accidents of the pump body and piping system will be caused. Therefore, install a safety return valve on the pump outlet pipe. When the pressure is too high, the valve will be opened to make the liquid petroleum gas flow back into the storage tank.
