Spherical Breathing Valves
WH-5102Q The valve is applied to pressure vessel pipeline system.
- Product Introduction
Spherical Breathing Valves are high-quality valves designed to provide reliable and efficient air flow control. These valves feature a unique spherical design that allows for smooth and precise operation, ensuring accurate metering of gases and fluids. The valves are constructed using durable materials that provide excellent resistance to corrosion and wear, making them ideal for use in harsh and demanding environments. Additionally, are equipped with advanced sealing technology that ensures reliable and leak-free operation, minimizing the risk of loss or contamination of volatile materials.
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. Conversely, it can close. The pressure regulating function is designed internally and the spherical cover is designed externally. When a vacuum
(standard - 0.2BAR) is generated in the pipeline system, the valve opens automatically, and the outside air enters the container to prevent the container from flattening. To ensure the safety and protection of equipment and related instruments, but also to meet the needs of a variety of production processes, the valve stainless steel material, health design, to meet a variety of food processing, beer, beverage and pharmaceutical industries.
How to adjust the working pressure of fermenter When pressure inside the fermenter is up to the working pressure, the safety valve will relief the valve. Usually, the working pressure is fixed to 2bar or 3bar. Sometime, m...
