D/PA(L)

Product Description

The D/PA(L) type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent flow performance. Typically, the valve is installed in the in-breathing and out-breathing lines of tanks, vessels, and process equipment to protect against unallowable overpressure and underpressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to the set vacuum. The product vapors can be released through a collective line connected to the line flange on the pressure side. Backflow is not possible, i.e. the valve can be used as an overflow valve or backflow protection.
