The FAV Systems Vapor-Tight Model VOR Vacuum Relief Vents are designed to relieve vacuum on tanks while they’re being pumped out or experience rapid climate changes resulting in the cooling and contraction of tank contents. Also available with flame arrestor for tank protection.
The vent is a one piece body design, which is an extremely rugged weld body unit. Taller guide rods ensure that a full open valve position is obtainable. All vents utilize FAV Systems Patented Counter-force Pressure Suspended Pallet and bolt in stainless steel seat and internal components.
