Groth Biogas - Model 8800 -Pressure Vacuum Valve and Flame Arrester for Biogas Systems
The Groth Model 8800 is a sophisticated pressure/vacuum relief valve and flame arrester designed to safeguard biogas systems from potential damage due to overpressure and excessive vacuum conditions. The device incorporates Groth's unique cushioned air seating technology and superior fluoropolymer seating diaphragms, minimizing the effects of resinous vapors and atmospheric moisture. The valve features self-draining housings and drip rings, which protect the seating surfaces against condensate buildup and freezing, thus ensuring reliable functionality in varying environmental conditions. Additionally, the integrated flame arrester offers protection from external heat sources and ignition, reducing emission levels and significantly enhancing fire safety. This model combines the reliability and efficiency of the 1200 Pressure Vacuum Relief Valve with the robust protection of the Groth Biogas Model 7618 Flame Arrester, making it a critical component for municipal, food & beverage, dairy farms, and landfill industries.
The Groth Model 8800 Pressure Vacuum Valve and Flame Arrester combination units are designed to protect your tank from damage created by over- pressure or excessive vacuum, at the same time that they provide protection from externally caused sources of heat and ignition. The result is increased fire protection and safety.
