Product Description & Applications: Sanitary pressure relief exhaust valve is a pressure relief safety valve. This particular model is also known as beer ferment exhaust air evacuation valve, because it is usually used on beer fermentation tanks. It can automatically discharge excessive air out of the sanitary tanks and pipelines, in order to keep the pressure inside the tank within allowable safety range. Working Principle: Step 1: Calibrate a specific pressure by adjusting the compression nut of the spring Step 2: Under normal operating pressure, the valve is closed Step 3: When the pressure inside storage tank is over the set pressure, the valve opens automatically Step 4: The pressure inside storage tank is released, the pressure value in pipe and equipment is restored to the set value range.   The glass cover is filled with water to seal the outlet hole. It is clearly visible through air bubbles in the glass cover when the valve discharges air out of storage tank. Configuration: Features:

1. Fast pressure adjustment, easy maintenance
2. Adjustable pressure control, can be adjusted within the safe range
3. Low-density PP material, this material will not be deformed even after soaking in high temperature water for a long time.
4. With bacteria filtering and dust-proof function
