• Dual Purpose Vent
• Roll Over Protection
• Compact Design
• Interior Mount
The Betts’ Normal Vent is the proven standard of the fuel transport industry. Normal Vents (breather vents) are utilized to normalize internal tank vacuum and pressure, which is critical to keep the cargo tank pressure within safe design limits. This vent incorporates a unique weighted roll-over block which increases the set pressure of the vent in a roll over situation but does not act as a shutoff device like other manufacturer’s designs. This feature differentiates the Betts’ design and allows the vent to maintain its primary function as a pressure/vacuum relief device in all situations. The vent is flow tested and marked in accordance with DOT requirements.
