WH-5102 Breathing Valve
Introduction to Functions and Characteristics
The valve is applied to pressure vessel pipeline system.
Breathing valve has two functions. When the pressure is higher than the set pressure (standard 1BAR), it can exhaust and turn off. When the vacuum (standard-0.2BAR) occurs in the pipeline system, the valve opens automatically to ensure the safety and protection of equipment and related instruments. At the same time, it can also meet the needs of various production processes. The valve is stainless steel. Material, sanitary design, satisfied with a variety of food processing, beer, beverage and pharmaceutical industries.
The valve is easy to take apart and clean. 15 lb. and 25 lb. pressure springs are available. Relief pressure can be adjusted down 5 lb. The valve will open at 0.089 lb. of vacumm. Full stainless steel body construction.
Stainlless steel sanitary pressure/Vacuum Relief Valves is a self-acting device, designed for keeping tanks to work properly. It could release air out of tanks to maintain pressure, and also absorb air into tanks to be anti-vacuum.
