High capacity weight or spring loaded pressure relief valves that vent to atmosphere. Designed to work closer to a tank's MAWP, increasing productivity, reducing emissions and product evaporation
Type 4130 valves allow tanks to work closer to their MAWP thus increasing productivity, reducing emissions and product evaporation. Increased flow capacities reduce the valve’s size, corresponding connections and piping costs in applications for storage tank farms, oil and gas production, the petroleum, pharmaceutical and chemical sectors.
