The VD/SV type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent ﬂow performance. Typically the valve is installed in the in- and outbreathing lines of tanks, vessels and process apparatus to protect against un- allowable high and low pressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to set vacuum.
