Storagetech 8211 Model 120 Pressure Vacuum Relief Valve

BRAND: StoragetechCATEGORY: Storage Tank Valves

The Storagetech Model 120 Pressure Vacuum Relief Valve also known as a Pressure Vacuum Vent or Conservation Vent, is a safety device designed to protect storage tanks or pressure vessels against overpressure pressure or excessive vacuum and to eliminate the evaporation of the tank contents to the atmosphere. The Model 120 has an outlet flange that enables hazardous vapours to be piped away rather than releasing them directly into the atmosphere. They are mounted to a flange or pipe on the storage tank above the vapour space. When air pressure exceeds the present setting of pressure vacuum vent, the pallet opens, lifts off the seal and expels any excessive negative or positive pressure. When air pressure exceeds the pre-set setting of the Pressure Vacuum Relief Valve, the pallet opens, lifting off the seal expelling any excessive negative or positive pressure.
