Breather Valve

Approx. Rs 15,000 / PieceGet Latest Price

The Tank Breather Valve is a critical safety and efficiency component designed for storage tanks, chemical vessels, and fuel tanks. It regulates internal tank pressure by allowing controlled venting of gases and vapors while preventing overpressure or vacuum conditions that could compromise tank integrity.

Key Features:

• Pressure and Vacuum Relief: Automatically maintains tank pressure within safe limits to protect against structural damage.

• Corrosion-Resistant Construction: Made from high-quality stainless steel, aluminum, or suitable alloys for chemical resistance and long service life.

• Flame Arrestor Options: Available with integrated flame arrestor for hazardous or flammable environments.

• Dust and Contaminant Protection: Filters incoming air to prevent contamination of stored products.

• Easy Installation and Maintenance: Designed for simple mounting and routine inspection without tank downtime.

• Wide Application Range: Suitable for oil & gas, chemical, pharmaceutical, water treatment, and food industries.

Applications:

• Storage tanks for petroleum products, chemicals, and solvents

• Fuel tanks for vehicles and generators

• Industrial process tanks requiring pressure/vacuum relief

• Water and wastewater storage systems

Benefits:

• Prevents tank deformation and leakage due to pressure fluctuations

• Enhances safety by reducing the risk of tank rupture or vacuum collapse

• Improves product quality by minimizing contamination

• Reduces environmental emissions by safely venting vapors

A Pressure Vacuum Breather Valve (PVBV) is a type of valve commonly used in storage tanks, especially for liquids like fuels, chemicals, or water. Its main function is to maintain safe pressure and vacuum levels inside a tank while allowing it to “breathe” air in and out as the liquid level changes.

1. Pressure Relief: If the tank is over-pressurized (for example, due to thermal expansion of the liquid or filling), the valve opens to release excess pressure.

2. Vacuum Relief: If a vacuum forms inside the tank (for example, when liquid is withdrawn or temperature drops), the valve opens to let air in, preventing the tank from collapsing.

3. Tank Protection: Prevents structural damage by keeping internal pressure within safe limits.

4. Emissions Control: Minimizes vapor release to the environment, which is important for volatile liquids like gasoline.
