Groth Model 8800A Pressure/Vacuum Valve & Flame Arrester

Groth Model 8800A Pressure/Vacuum Valve & Flame Arrester

Product Description
The Groth Model 8800A is an end-of-line Pressure/Vacuum Relief Valve combined with a high-performance flame arrester. This integrated unit is engineered to protect storage tanks from overpressure or excessive vacuum while preventing flame propagation from external ignition sources. By utilizing cushioned-air seating and corrosion-resistant components, the 8800A ensures reliable sealing, reduced emissions, and enhanced fire safety.

The assembly consists of the Groth 1200A Pressure/Vacuum Relief Valve paired with the 7618 Flame Arrester. Its self-draining design, drip rings, and non-sticking fluoropolymer diaphragms provide dependable operation even in demanding conditions involving resinous vapors or moisture.

Key Features

• Cushioned Air Seating for smooth and reliable valve operation.

• Fluoropolymer Seating Diaphragms to minimize sticking caused by resinous vapors or atmospheric moisture.

• Self-Draining Housing with Drip Rings to prevent condensate buildup and freezing.

• Integrated Flame Arrester using a spiral-wound, crimped ribbon flame element for effective flame quenching.

• Modular Construction for easier maintenance and component replacement.

• Suitable for NEC Group D and IEC Group IIA gas service.

• Pre-Ignition Pressure: Atmospheric.
