The ELEVENT® pressure and vacuum relief valve provides optimum protection against overpressure and vacuum for tanks and vessels with low design pressures. It assures a constant and controlled level of pressure in the tank. ELEVENT® not only prevents fugitive emissions of gas, or other pollutants, but also prevents the development of explosive mixtures of substances. Further the valve eliminates the potential danger of air entering the system. The standard operating ratio is up to 95 % of the minimum response pressure. ELEVENT® is used in the oil and gas industries, the chemical and pharmaceutical sectors, the food processing and in power plant technology. The optimised ”air cushion“ sealing principle provides a smooth valve stroke and an extremely reliable leak-tight seal. This prevents valve chatter and abrasion. The metal housing is made from deep-drawn stainless steel.
