mod.SIG\/63 series Pressure vacuum relief valves begin opening at the set vacuum level and fully open at about 10% over the set point. They begin closing as the vacuum level drops and fully close when the system is restored below the set point. Adjust the set vacuum level within the range. Valves have a vented relief port to exhaust discharge directly.<\/p>\n<\/div>\n
