Pressure/Vacuum Relief Valve and Flame Arrester w/ Safety Diverter Valve

Model 8800SDV

Pressure/Vacuum Relief Valve and Flame Arrester w/ Safety Diverter Valve

The Safety Diverter Valve (SDV) is a 3-way, multi-port ball valve, offering a safe, quick and easy way for valve “changeover” used quite commonly on bio-digesters for ease of inspection, maintenance and cleaning. This allows for redundant pressure vacuum relief valve (PVRV) and flame arrester (FA) assemblies allowing no process interruption, while  providing  continuous  system overpressure or vacuum protection due to pumping-in (influent) and pumping-out (effluent). The design makes it impossible to shut-off both valve outlets at the same time which guarantees continuous operation.
