• PRESSURE/VACUUM RELIEF VALVES

Pressure/vacuum relief valves are protection devices typically mounted on a nozzle opening on the top of a fixed roof atmospheric storage tank. Their primary purpose is to protect a tank against rupture or implosion by allowing the tank to breathe, or vent, when pressure changes in the tank due to normal operations.

Technical data: Groth Corporation Series 1400 - Pilot Operated Pressure/Vacuum Relief Valve.

Technical data: Groth Corporation Series 1200A - Vent to Atmosphere Pressure/Vacuum Relief Valve.

• PILOT OPERATED RELIEF VALVES

Pilot operated relief valves serve the same primary purpose as pressure/vacuum relief valves, but with better performance characteristics than weight or spring loaded valves. Lower leakage and better flow performance make a pilot operated valve the solution when the focus is product conservation, expanded tank working pressure range, and reduced fugitive emissions. A pilot operated relief valve provides the maximum available leakage control technology as specified in the Clean Air Act of 1990.

Technical data: Groth Corporation Series 1660A - Pressure Relief Pilot Operated Valve. 

Technical data: Groth Corporation Series 1400 - Pilot Operated Pressure/Vacuum Relief Valve.

• EMERGENCY RELIEF VALVES

Emergency relief valves protect tanks against excessive pressure caused by external fire exposure or flashes within the tank. Emergency relief valves provide higher flow capacity than standard pressure/vacuum relief valves. 

Technical data: Groth Corporation Series 2300A - Pressure Relief Valve. 

Technical data: Groth Corporation Series 2000A - Emergency Relief Valves.

Technical data: Groth Corporation Model 2100 - Emergency Relief Valve.

• DEFLAGRATION FLAME ARRESTERS

Deflagration flame arresters are fire safety devices used to protect stored or process media from deflagrations. A deflagration flame arrester can be used on the top of a tank in certain conditions,  as an in-line safety device where combustible gases are transported through low pressure pipe lines. 

Technical data: Groth Corporation Model 7618 - Vertical Deflagration Arrester. 

Technical data: Groth Corporation Model 7628 - Horizontal Deflagration Arrester. 

Technical data: Groth Corporation Model 7622B - Deflagration Arrester. 

• DETONATION FLAME ARRESTERS

Detonation flame arresters provide flame protection in cases where the ignition source pipe lengths are greater than what can be protected with a deflagration arrester.

Technical data: Groth Corporation Model 7658A - Detonation Flame Arrester. 

Technical data: Groth Corporation Model 7661 - Detonation Flame Arrester.

Technical data: Groth Corporation Model 7758A - Detonation Flame Arrester.

• BLANKET GAS REGULATORS

Blanket gas regulators can provide both pressure and fire protection for storage tanks by supplying a blanketing gas which maintains a constant positive pressure in the vapor space of a storage tank.

Technical data: Groth Corporation Series 3000 - Blanket Gas Regulator.
