Series 1800A is a relief valve that attains full stable lift at only 10 percent overpressure. The full-lift-type valve is designed for applications requiring low emissions and operation near tank maximum allowable working pressure (MAWP). The modulating valve offers near zero blowdown and reseats at near set pressure. Operating within 10 percent of the tank MAWP greatly reduces the breathing losses of the product in the tank.
