- Product Introduction
The 3.5 inch Breathing Valve is a revolutionary product designed to improve airflow while reducing breathing resistance in a variety of scenarios. This unique product features a high-quality valve design that allows for easy breathing and improved air circulation, making it perfect for athletes, medical professionals, and anyone who wants to breathe easier. The valve is made from durable materials and is designed to be easy to clean and maintain.
Product Description:
Sanitary pressure relief breathing valve, also known as air filter, is installed in fermentation tank, storage tank, batching tank and distilled water tank. It can filter fermentation air, inert gas and other medium in and out of the tank to ensure the medium in the tank is aseptic. The sanitary rebreathing valve is specially used for tank gas exchanging in pharmaceutical industry and food industry.
Working Principle:
Step 1: Set the working pressure within the specific range
Step 2: When the tank medium pressure is within the set pressure range, the valve doesn't work, to maintain the tightness of the tank
Step 3: Add the medium into the tank, the medium pressure increases and valve will open, letting the medium comes out from the valve outlet, in order to prevent the tank pressure continuing increasing
Step 4: Remove the medium out of the tank, and the tank pressure drops below the set pressure range, the air outside the tank passes through the rebreather valve and is also filtered as well, in order to balance the medium pressure inside and outside the tank
