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.

The safety valve is used to used to keep the set pressure in the system. When the system pressure is higher than set pressure, valve open to reduce the pressure.

Before the valve is dispatched, we have set the pressure to given pressure. The valve is closed.
If needed, we can install a pressure gauge before the inlet of safety valve.

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

Highlights:

1. Medium filtration accuracy: 0.1 ~ 100μm optinal, efficiency 99.99%
2. Filter capacity (displacement) in the range of 0.1 ~ 100 M3 / minute optional
3. Filter device pore diameter is uniform and stable, low air resistance
4. Filter element service life up to 2 ~ 3 years, and can be extended to 4 ~ 6 years after regeneration
5. High temperature resistant, can filter the steam used for sterilization
6. Size, height, wall thickness, pressure can be customized
