Description

The OPW 301M-3081 3" Male NPT Emergency Vent is designed to prevent an above ground storage tank from becoming over-pressurized by providing high-capacity venting in the event of a fire or blockage. The 301 is a weighted, mushroom-style emergency vent. When the AST builds pressure, the weighted cast iron lid is forced up off its seat to relieve the pressure. When pressure is relieved, the lid lowers and is automatically reset.

Features

Automatically Resets – weighted cast iron cover reseats once the pressure in the tank is relieved.
Aluminum Body and Cast Iron Lid
Epoxy Powder-Coated Cover – prevents rusting of the cover to protect expensive finishes on ASTs.
Mounting connection: 3" Male NPT
Pressure Setting: 8 oz.
Height: 4.7 in (119.4 mm)
Width: 5.1 in (129.5 mm)
