Relief Valves

Relief Valves

Relief Valve attains full stable lift at 10% overpressure.

Available in 2 in. (DN 50) through 12 in. (DN 300) flange sizes, 1800 A series full lift type valve is suited for applications requiring low emissions and operation near tank maximum allowable working pressure (MAWP). Modulating valve offers near zero blowdown and reseats at near set pressure, while reducing breathing losses of product in tank.
