Groth Biogas - Model 8800SDV -Safety Diverter Valve for Biogas Systems

SHARE
The Groth Biogas Safety Diverter Valve (SDV) is a crucial component specifically designed for bio-digester systems. This 3-way, multi-port ball valve facilitates seamless valve changeovers, ensuring ease of inspection, maintenance, and cleaning without process interruption. The valve integrates with redundant systems like pressure vacuum relief valves (PVRV) and flame arresters (FA) to provide continuous protection against system overpressure or vacuum conditions caused by variances in influent and effluent pumping. Its application spans across various industries, including municipal waste management, food and beverage production, dairy farms, and landfill gas management, highlighting its versatility in managing biogas systems safely and efficiently.

The Groth Biogas 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).

  • 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
