Relieve excess pressure or vacuum with one valve that can be configured for either application. These valves begin opening at the set pressure or vacuum level and fully open at about 10% over the set point. They begin closing as pressure or vacuum level drops and fully close when the system is restored below the set point. Adjust the set pressure or vacuum level within the range. Valves have a vented relief port to exhaust discharge directly.
