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
ncreased flow capacities reduce the required valve size and the corresponding connections and piping costs.Fully open at 10% overpressure, enabling setting close to MAWP and minimizing tank emissions.Large body for increased capacity providing high flow performance for full conformance to API2000/ISO28300.Leakage rate of 0.5 scfh (0.015 Nm3 /hr) or less at 90% of setpoint.Weight or spring loaded models available.Choice of body materials.Modular design enables all components to be removed and replaced in-situ for quicker, simpler maintenance.Optional ‘all-weather’ coating prevents frozen condensate build-up and sticking of vital components in cold weather applications.
