Vacuum negative-pressure safety valve Characteristic use

HFA72W is applicable in negative pressure sys-tem with temperature ≤200℃. When the negative pressure in the container exceeds the allowable value, the valve will open automatically and absorbs air; when the negative pressure in the container reaches the allowable value, the valve will close au-somatically so as to protect the equipment and the system. It is to be installed in normal non-negative pressure systems. When the discharge valve of the container and system has not opened, which pro-dukes the negative pressure, this valve will open automatically.
