- Integral relief valve/10" fill
- Less than 1 Liter Leakage
- Set Pressure Adjustment
- Increased Flow Rate
- Secondary Safety Latch
The integral 10" Relief Valve provides emergency pressure relief and meets the 1 liter surge leakage limit imposed by 49CFR178.345-10(b)(3)(ii). The relief valve also serves as a 10" latch style fill which can be easily opened to provide access for filling the tank or for inspection. Relief valves contain an adjustment feature to allow for fine tuning of set pressure in the field. Other standard features include a heavy duty clamp ring, secondary safety latch and model 6496ALB pressure-vacuum vent mounted in the 10" relief valve cover.
Manholes are available with a self-latching feature that allows the 10” relief valve/fill cover to drop and securely latch upon movement of the tank if the cover is inadvertently left open.
Manhole collars are available in aluminum, steel, and stainless steel. When welding collars to tank, care should be exercised to insure collar remains flat and round.
