1200A Biogas Pressure Vacuum Relief Valve

FEATURES

  • Peripheral and central seat guides ensure reliable, repeatable performance
  • A wide seat and air-cushion seal keeps leakage low long after the valve is put in service
  • Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
  • Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture

The Groth Biogas Model 1200A biogas pressure vacuum relief valve is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the Model 1200A retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety.
