Working Principle
When the internal pressure of the vessel is higher than the set pressure, the valve will automatically open to vent outside the vessel, otherwise the valve will close. when a negative pressure is generated in the container,the valve will automatically open to inhale into the container; prevent the container from deforming.The valve has functions of exhalation and inhalation.which greatly reduces the cost of the system of the container and the pipeline.
2.5 inch Breathing Valve is a device that can be used with a wide range of respiratory protective equipment, such as face masks and respirators, to help regulate breathing and protect against harmful airborne particles. The valve is designed to allow easy inhalation and exhalation while also preventing the entry of hazardous particles into the respiratory system.
The 2.5 inch Breathing Valve is made of high-quality materials, such as silicone and plastic, and generally consists of a base, a valve disc, and a cover. The valve disc is located at the center of the base and is responsible for regulating the flow of air in and out of the mask or respirator. The cover is designed to protect the valve disc from external particles and moisture, ensuring that the valve remains functional and effective.
This type of breathing valve is particularly useful for workers who are exposed to airborne hazards, such as dust, fumes, and other particulates, in their day-to-day work. By regulating the flow of air, the valve helps to ensure that workers do not inhale harmful particles and that they remain protected while performing their tasks.
