Breather Valve

Breather Valve

Fidicon Devices India's breather valves are designed to provide reliable protection against overpressure or vacuum conditions while allowing for the free flow of air or gas in and out of the tank or vessel. They are available in various materials, including stainless steel, aluminum, and brass, to ensure compatibility with different types of fluids and environments.

Type Of Breather Valve

• Pressure Vacuum Breather Valve
• Pressure Only Breather Valve
• Vacuum Only Breather Valve
• Breather Valve With Flame Arrestor

Pressure / Vacuum Breather Valve

Size :	1″ to 30″, Type : Dead Weight Loaded, Spring Loaded
Type :	Pressure Vacuum Breather Valve
Body Materials :	Aluminium Alloy and CS for 2″ to 16″ sizes and Cast Steel.
Set Pressure :	50mm H2O to 2000mm H2O

The top two mechanisms will function as a combined pressure/vacuum breather valve once they are merged into a single unit. It functions using the same idea.

One sort of breather valve is the emergency vent valve. The evaporation rate will increase and the standard pressure breather valve won't be sufficient if the outside temperature rises unexpectedly during a fire emergency or reaction runaway in the tank. The emergency vent valve, which has a slightly higher set point in this circumstance, will open up and immediately release the pressure.

Pressure Only Breather Valve

Size :	1″ to 36″, Type : Dead Weight Loaded, Spring Loaded
Type :	Pressure Breather Valve
Body Materials :	Aluminium Alloy and CS for 2″ to 16″ sizes and Cast Steel.
Set Pressure :	53mm H2O to 2000mm H2O

On the storage tank's roof, a pressure-only breather valve is employed to handle high pressure situations. Regardless of whether the valve is weighed or spring-operated, if the pressure rises above the predetermined value, it will open and maintain the normal pressure.

Vacuum Only Breather Valve

Size :	Size : 1″ to 32″, Type : Dead Weight Loaded, Spring Loaded
Type :	Vacuum Breather Valve
Body Materials :	Aluminium Alloy and CS for 2″ to 16″ sizes and Cast Steel.
Set Pressure :	55mm H2O to 2000mm H2O

Additionally, a vacuum-only breather valve is installed to the storage tank's ceiling. When a vacuum is created and the pressure drops below the preset value, the valve will open and maintain pressure by allowing air to be breathed in.

Advantages Of Breather Valve :

• Protects the tank from implosion and explosion
• Provides safety to pumping operation
• Low maintenance
• It prevents fire hazard
• Prevent vapour loss (save cost)
