Fluidyne Emergency Vent and Manhole Cover is a safe solution to emergency venting requirements where intermediate pressure settings are required. Fluidyne Emergency Vent and Manhole Cover design employs a tight seal between the pallet and the corrosion resistant seat below set pressure and assures low leakage.When set pressure is reached, the pallet lifts. Flow efficiency rises rapidly to approximately 100% at higher overpressure the flow efficiency. For tank venting or examination, the entire hinged cover can be quickly lifted open offering clear passage and unobstructed opening. Pallet construction permits a wide range of pressure settings. Fluidyne Emergency Vent and Manhole Cover Standard design is available in 10", 16", 18", 20", 24", 30" and 36" sizes. The Standard Mounting Flange is API 650 and 150lb ANSI Flat Face. The body has lifting ears to lift and position the unit (not avialable on 10" and 16" sizes). The 20" and 24" vents can be provided with flat face flanges to fit API 650 Roof Manholes.
