Petroleum Manhole Cover
The Ventris Pressure-Activated Fill Cover (PAF) is made from high-strength aluminum, providing protection against rust, as well as weight reduction. Ventris' Manhole Cover weighs up to 30% less than competitive DOT406 Manhole Covers on the market today.
The 10" PAF is factory set to open at 25 kPa, and features easy-set pressure adjustability without the worry of compromising emergency-venting capacity.
The Ventis Manhole Cover is the perfect choice for new construction, or as a replacement for all older manholes on existing cargo tanks. It meets China Auto Industry standard QC/T requirements.
