PRODUCT DATA SHEET The 2” High Flow PV Vent provides pressure venting to atmosphere, for the tanker vapour line when it is not sealed, for vapour transfer. The pneumatic cylinder seals the vent when vapour transfer is required. Aerodynamic porting facilitates extremely high throughput. Pressure: Air flow at 21 kPa = 198200 litres per hour (7000 cubic feet per hour). Mandatory rollover seal off is included. This feature has proven its effectiveness many times in tanker rollover accidentswhere it has protected lives, prevented dangerous, costly spillages and stopped pollution. F0454| COAMING/VAPOUR LINE VENT VALVE F0454 FEATURES AND BENEFITS High flow through wind tunnel tested aerodynamic porting. Pressure actuated at 70mbs (7kPa) – other pressure settings are available on request. Seal off device prevents product spillage in tanker rollover accidents. Exceeds the requirement of petroleum spirit conveyance by road regulations. Viton seals are standard for compatibility with high-octane fuels. Flame retardant stainless steel gauze covers the inlet/outlet ports. * * * * * *
