Micro-open safety valve refers to a type of safety valve with relatively small disc opening height and discharge amount. Specifically, the specified opening height of the valve disc h is between D1/40 and D2/20 (D1 is the diameter of the valve seat throat).


Full-opening safety valve refers to a safety valve with an opening height greater than or equal to 1/4 of the diameter of the flow channel. The operating characteristics of this safety valve belong to the two-stage acting safety valve
