Sanitary Pressure Relief Breathing Valve

Product Detail

Product Description: Sanitary pressure relief breathing valve is installed in fermentation tank, storage tank, batching tank and distilled water tank, to keep the medium inside the tank isolated from outside within a set pressure range, and also connected with outside when pressure inside the tank exceeds or drops under the set level. It is an very ideal valve to protect the tank from being damaged due to over pressure or vacuum status, in the meanwhile keeping medium from evaporation loss. The pressure relief breathing valve consists of valve seat, valve cover, protection cover and two sets of open-close devices each controlled by vacuum and pressure. When pressure inside the tank exceeds positive pressure level, pressure valve disc opens and the air goes outside breath out Functions & Applications: It is used to balance the pressure between inside and outside the tank, in order to make sure the tank under safe pressure range. Sanitary pressure relief breathing valves are designed for pharmaceutical, water treatment, food industries. Our air release breather valve are in full compliance with GMP standard, and are very suitable for air for injection, inactive gas, and distilled water. 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 air comes out from the valve outlet holes, 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 negative pressure level, the air outside the tank passes through the breathing valve, in order to prevent the tank pressure continuing dropping.   This pressure relief breathing valve can realize breath in and breath out, in order to balance the medium pressure inside and outside the tank.
