Introduction to a72w-10p/r vacuum negative pressure safety valve

A72w vacuum negative pressure safety valve is applicable to the negative pressure system with temperature ≤ 200 ℃. When the negative pressure in the container exceeds the allowable value, the valve will automatically open and inhale air; When the negative pressure in the container reaches the allowable value, the valve will automatically close to protect the equipment and system. It is installed in the normal non negative pressure system. When the vent valve of the container and system is not opened and negative pressure is generated, this valve will open automatically.
