Product introduction
The imported breather valve produced by Breer can be driven by automatic, flanged by connection, piped by structure, PTFE by sealed structure, PN150-300LB pressure range, nominal dia
meter DN25-250mm, material can be Use cast iron, WCB, stainless steel, etc. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
The inlet breathing valve works according to the principle:
The first is to exhale or inhale when a certain pressure is reached; the other is designed to simply not breathe, which can be understood to be replaced by two check valves of appropriate pressure.
The second type of breathing valve is similar to a one-way check valve. It can only exhale outwards and cannot inhale inward. When the pressure in the system rises, the gas is vented through the breathing valve to ensure a constant system pressure. For storage tanks containing toxic substances, there are no breathing valves, or treatment devices such as activated carbon
filters are added.
