What Are Flame and Detonation Arresters, Pressure & Vacuum Relief Valves, and Blanket Gas Regulators?
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 pro-vides the maximum available leakage control technology as specified in the Clean Air Act of 1990.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.BLANKET GAS REGULATORS
Blanket gas regulators can provide both pressure and fire protection for storage tanks by supplying a blanket- ing gas which maintains a constant positive pressure in the vapor space of a storage tank.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.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.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.Tri-State Technical Sales represents Groth Corporation.
