A72W vacuum negative pressure safety valve is suitable for negative pressure systems with a temperature ≤ 200℃. When the negative pressure in the container exceeds the allowable value, the valve automatically opens to suck in air; when the negative pressure in the container reaches the allowable value, the A72W vacuum negative The pressure safety valve is automatically closed to protect the equipment and system. Installed in a normal non-negative pressure system, this valve will automatically open when the container and the system's relief valve are not opened and negative pressure is generated.
The purpose of A72W vacuum negative pressure safety valve:
1. Used in negative pressure system: When the negative pressure in the negative pressure container system exceeds the allowable value, the valve will automatically open to inhale air. When the negative pressure drops to the specified value, the valve is automatically closed to ensure the safe operation of the equipment container and system;
2. Used in normal non-negative pressure systems: various corrosive media containers, such as absorption towers, distillation towers, storage tanks, tanks, etc., when steam is introduced for cleaning, if the relief valve is not opened, the steam will condense, resulting in negative pressure. The installation of the equipment is to ensure the safety of the equipment.
