MIFAB, Inc. > PRODUCT > AV-MH Air Release and Vacuum Break Valve

The standard Beeco Air and Vacuum Valve (K) exhausts large quantities of air when the system is filling. The valve will remain open until the liquid has reached the float and is lifted into its seat, closing the valve. Likewise when a vacuum occurs, the float will drop, allowing air into the system to prevent pipe collapsing due to the negative pressure.
