304 Pressure Vacuum Valve Stainless
WH-5102
- Product Introduction
The 304 Pressure Vacuum Valve Stainless is a unique product designed to ensure that high-pressure and vacuum levels within a vessel are maintained at safe and preset levels. The valve is made of high-quality stainless steel, making it highly durable and resistant to corrosion. Its compact size makes it easy to install on a range of tanks, including food and beverage production tanks, pharmaceutical vessels, and chemical storage tanks.
The pressure vacuum valve also features a range of useful functions, including adjustable pressure and vacuum settings, as well as an emergency pressure release mechanism. This ensures that any excess pressure or vacuum levels within a tank can be efficiently and safely released if required.
working principle
When the positive pressure value in the container is greater than the pressure value set by the positive pressure spring of the valve, the valve will automatically open to exhaust the outside of the container. When the positive pressure value in the container is lower than the pressure value set by the positive pressure spring of the valve, the valve will be closed; When the vacuum negative pressure value generated in the container is greater than the negative pressure value set by the valve, the valve will automatically open and inhale into the container. When the vacuum negative pressure value generated in the container is lower than the negative pressure value set by the valve, the valve will be closed. This breathing valve can realize the double action of breathing and breathing, effectively protecting the system safety of containers and pipelines.

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.
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.

为保证开启压力值准确，应使调整时的介质条件，如介质种类、温度等尽可 能接近实际运行条件。介质种类改变,特别是当介质聚积态不同时(例如从液相变为气相),开启压力常有所变化。工作温度升
高时，开启压力-般有所降低。故在常温下调整而用于高温时，常温下的整定压力值应略高于要求的开启压力值。高到什么程度与阀[ ]结构和材质选用都有关系，应以制造厂的说明为根据。
