Under normal practice, vent is closed When loading and unloading and temperature variation, it will cause the pressure variation inside the tank, such as air pressure and negative vacuum pressure, the vent of manhole cover will be closed automatically in order to keep the tank under a normal pressure. 4) When involving in emergency, such as a car accident, the Emergency Exhaust Valve will open the inside tank, meets the setting, in order to prevent explosion.
Standard:
Meet the NTTC DOT406 Standard
Meet the International GB18564.1 Standard
Lever, Cover & Weld Ring: galvanized seel
Emergency Exhaust Valve Aluminum Alloy
Seal Ring： ：Nitrile or fluoro
The emergency vent cover be compressed in eccentric way to avoid accidents due to overpress
Vent with spring can open automatically, which meet NTTC DOT406, can avoid the explosion effectively。
Automatic sealing of the P/V vent in a roll over situation prevents dangerous and costly spillage.
Two-stage opening allows safe release of residual compartment pressure before fully opening the fill cap.
250mm(10)fill hole for easy drop pipe insertion when top loading.
Setting pressure of vent discharge：6~8kpa
Negative opening pressure：-2~-3kpa
Setting pressure of emergency exhaust valve：23~26kpa
Pressure resistance：0.254Mpa
