Vacuum Relief Valve
WH-5102Q
The valve is applied to pressure vessel pipeline system.The valve is applied to pressure vessel pipeline system. Breather valves are safety devices required for storage tanks/containers/gas or vapor pipe lines/reactors etc. having chemicals or any other fluid to be handled carefully. Breather valves with desiccants are used during transportation of sensitive equipments/goods to protect from pressure differentials due to change in climatic conditions.Combustion research associates manufacturers Pressure Vacuum Relief Valves(PVRV),Breather Valves, Safety Relief Valves and Vacuum Breather Valves-of wide range to meet the industry requirements. In case of combustible fluids storage the safety valves should be used along with flame arrestors.
- Product Introduction
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.

A Vacuum Relief Valve is a safety valve that is installed in a pipeline or a piece of equipment to prevent the pipeline or equipment from collapsing due to excessive vacuum pressure. This is achieved by releasing the excess vacuum pressure when it reaches a certain level through the valve. The valve is designed to remain closed under normal conditions, but once the vacuum pressure exceeds the set limit, the valve opens automatically to release the pressure.
The commonly used in systems that are subject to sudden and extreme changes in temperature, such as refrigeration and air conditioning systems. It is also used in systems that move fluids, such as water and oil, where the fluid can cause a vacuum in the pipeline or equipment under certain conditions.
The design and construction of a vary depending on the application and requirements. Some valves are designed to discharge the escaping gas or fluid into the atmosphere, while others divert the escaping fluid to a separate storage tank. The materials used to manufacture the valves must be compatible with the fluid and the environment in which they operate. Some valves are made of stainless steel, while others are made of plastics or other materials.
