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…
