301 SERIES EMERGENCY VENTS
OP.AST.301
› 301 Emergency Vent is designed to prevent an
above ground tank from becoming pver-pressurized by
providing high-capacity venting in the event of a fire or
blockage
› It is a weighted, mushroom-style vent. Cast iron lid is
forced up to relieve the presure and reseats by its own
weight once the pressure is relieved

male NPT or flanged connections
› Options to have either 32 or 64 mbar pressure set
values
202 SERIES EMERGENCY VENTS
OP.AST.202
› 202 Emergency Vent is designed to prevent an
above ground tank from becoming pver-pressurized by
providing high-capacity venting in the event of a fire or
blockage
› When the ast builds pressure to 0.17 bars, the springloaded
lid opens full-bore and discharges vapors
› The lid remains open to indicate a problem until
manually reset.
› Supplied with 4”, 6”and 8” with female NPT thread
connection

thermal expansion via its internal pressure relief valve.
Set to operate between 1.3 to 2.7 bar
› Temprature rating of -49 +29 degree celcius
› Supplied with 3/4”, 1”, 1.5” and 2” with female NPT
thread connection
821 SOLENOID VALVE
OP.AST.821
› Helps preventing siphoning of an ast should a leak
