- Product Introduction
Sanitary Breathing Valve Safety Valve Series is designed to maintain proper pressure and prevent overpressure and vacuum formation in storage tanks, pipelines, and other applications in the food, beverage, pharmaceutical, and chemical industries. Made from high-quality stainless steel, these valves have a compact design, easy installation, and easy maintenance. The valves feature a sanitary design to enhance reliability and durability, as well as to maintain the cleanliness of the system. The has a high-precision pressure control function that ensures accurate settings and a safe, reliable system operation. It also has a compact size, which is suitable for limited spaces and is easy to clean.
Introduction to functions and features
The valve is used in pressure vessel piping systems
Breathing valve has two functions, when the pressure is higher than the set pressure (standard 1 BAR) can exhaust, whereas closed, while vacuum piping system (standard 0.2 BAR) when the valve opens automatically, to ensure the safety of the equipment and related instrumentation protection, at the same time can also meet the demand in all kinds of production process, the valve in stainless steel material, health design, content with all sorts of food processing, beer, beverage and pharmaceutical and other industries.
Working principle
When the positive pressure value in the vessel is greater than the set pressure value of the valve positive pressure spring, the valve will automatically open to vent outside the vessel. When the positive pressure value in the vessel is lower than the set pressure value of the valve positive pressure spring, the valve will be closed. When the negative pressure value of the vacuum generated in the vessel is greater than the set negative pressure value of the valve, the valve will automatically open to inhale into the vessel. When the negative pressure value of the vacuum generated in the vessel is low When the negative pressure value is set for the valve, the valve is closed. The breathing valve can realize the double functions of respiration and suction, effectively protecting the system safety of containers and pipes.
Applications
The safety valve is the sanitary stainless steel valve.its safety design make it protect the equipment,so it installed in the return circuit of discharge pressure,it’s good for safety function in pipeline,pump,device,storage tank.Extensively applied to food,beverage,dairy,beer industry,etc.
Operating Principle
Under normal operating conditions,the valve remains closed.The specific pressure is set by adjusting the spring with the pressure nut.When the pressure in the pipes is above the specific pressure,the valve becomes open automatically to make the liquid pass over in order to reduce the pressure in the pipes.
Standard Design

Sanitary Breathing Valve Safety Valve Series is a comprehensive range of valves that are designed to ensure optimal functioning of sanitary systems in various industries. This series is particularly important in industries that require the transfer of fluids and gases, such as the food and beverage or pharmaceutical industries, where cleanliness and hygiene are of utmost importance.
The Sanitary Breathing Valve Safety Valve Series includes a variety of high-quality products, such as pressure relief valves, vacuum relief valves, and air release valves. These valves are designed to control and regulate the pressure inside the system, ensuring maximum operational efficiency.
The pressure relief valves are particularly important in preventing the over-pressurization of the system. They can be adjusted to open and release pressure at a designated pressure level, which minimizes the risk of damage to equipment and the system itself.
Vacuum relief valves, on the other hand, are designed to prevent the creation of a vacuum in the system by allowing air to enter the system. This is crucial to ensure the optimal flow of fluids and prevent the collapse of tanks or pipelines.
Air release valves are designed to remove air from the system, which can improve the transfer of fluids and reduce the risk of clogging or blockages. They also prevent air pockets from forming, which can lead to inaccurate readings and cause inefficiencies in the system.
Overall, the Sanitary Breathing Valve Safety Valve Series is a reliable and high-quality range of valves that are essential in ensuring optimal operation of sanitary systems. With their innovative design and high-performance features, these valves provide peace of mind for organizations in various industries, making them an indispensable component of any sanitary system.
