Sanitary Stainless Steel Tank Pressure Vacuum Relief Valve
WH-5102 2" It 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.
- Product Introduction
The Sanitary Stainless Steel Tank Pressure Vacuum Relief Valve is designed to maintain the pressure and vacuum levels within a sealed tank to ensure safe and efficient operations. Made of high-quality stainless steel, this valve is hygienic, durable, and corrosion-resistant, suitable for use in food, beverage, pharmaceutical, and chemical industries.
This valve ensures that the tank pressure remains within a safe range by automatically opening or closing depending on the pressure levels. Its adjustable pressure relief range and vacuum settings make it highly adaptable to different tank types, sizes, and operating conditions. It also features a compact and lightweight design, making installation and maintenance easy and convenient.

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.
Use stainless steel vacuum safety valve to automatically release tank pressure
The vacuum relief valve stabilizes pressure with preset pounds per square inch (PSI) settings on the vacuum and pressure sides. When the pressure inside the tank on the vacuum side exceeds 0.15 PSI, the valve will automatically open to relieve the pressure, drawing air into the tank. Conversely, when the pressure outside the tank exceeds 15 PSI, the valve opens and vents air outward. This maintains the pressure within the tank system at the desired level.

Sanitary stainless steel tank pressure vacuum relief valve is an essential component used in various industrial processes. It is installed on the tank to control the pressure and vacuum environment inside the tank. This valve can operate automatically in response to changes in pressure or vacuum inside the tank. It is designed to keep the tank safe by preventing over-pressurization or over-vacuuming.
The valve is made of high-quality stainless steel, making it corrosion resistant and durable. The use of stainless steel ensures that it meets the highest sanitary standards and can be used in applications that require sterile and hygienic processing. The valve is easy to clean and maintain, ensuring that it remains in optimal working condition for an extended period.
The Sanitary stainless steel tank pressure vacuum relief valve comes in various sizes and configurations, depending on the application. The valve is available in a threaded or flanged design and can be used to vent to the atmosphere or connect to another vessel. The valve can also have a pressure gauge or a handle to adjust the setting according to the desired pressure or vacuum.
