A valve assembly for fluid control comprises a main valve body, a passive valve, an automatic valve, a first check valve, and a second check valve. The main valve body comprises a first fluid path, a second fluid path, and a third fluid path. The first fluid path is installed in the entrance of a high pressure container. Charge raw gas passes through the first fluid path. Supply raw gas passes through the second fluid path. The third fluid path is connected to the first fluid path and the second fluid path. The passive valve is installed in the main valve body and opens the third fluid path. The automatic valve is installed in the main valve body and opens the second fluid path by using electric signals. The first check valve is installed in the first fluid path and blocks the reverse inflow of the charge raw gas. The second check valve prevents the inflow of the charge raw gas to the automatic valve by blocking the reserve inflow of the charge raw gas and blocking the inflow of the charge raw gas to the second fluid path. The present invention is provided to block applying high charge pressure to the automatic valve, thereby preventing the damage of the automatic valve and malfunction. |
