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).

Features

  • 3-way, multi-port, full bore design
  • L Port (90 degrees)
  • Live-loaded stem packing for positive sealing (sizes 6″ and larger)
  • High sphericity and mirror surface finish of ball ensures positive shut-off and low operating torque.
  • Handlever (sizes 2″ thru 4″), gear-operator (sizes 6″ and larger)
  • Visual indicator for indicating active relief valve and flow path of the media
  • Lock-out mechanism (standard) prevents unwanted access
  • Stopping mechanism prevents shutting off both valves at the same time
  • Ability to perform maintenance without interrupting service or vessel protection
  • Flow area is never restricted
  • Balanced internal forces
  • Smoother valve shifting
  • Able to apply pressure to any port

Size: 2″ thru 10″

Material: Available in carbon steel and stainless steel
