Breather Valve Manufacturer & Supplier in India
Fidicon Devices India is a manufacturer and supplier of breather valves, also known as pressure/vacuum relief valves or conservation vents. Breather valves are used to protect tanks, vessels, and pipelines from overpressure or vacuum conditions that can occur due to changes in temperature, atmospheric pressure, or fluid transfer.
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.
What Is Breather Valve ?
Breather Valves, additionally called direct acting Pressure/Vacuum Relief Valves, ar special kinds of Relief Valves that ar specifically designed for tank protection. The vary includes pressure solely, vacuum solely, combined Pressure/Vacuum Valves and combined Pressure/vacuum valves with pipe-away, all on the market with flanged shops or ventilated to atmosphere. Pressure/Vacuum Relief Valves ar used extensively on bulk storage tanks to reduce evaporation loss. The Valves stop the build-up of excessive pressure or vacuum which may unbalance the system or harm the storage vessel. Pressure and vacuum protection levels ar controlled with weighted pallets or springs and might be combined to supply the specified Pressure/Vacuum settings. it's common to mix pallet and spring systems in one unit i.e. pressure settings need a spring section, while the vacuum settings use the pallet technique.
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
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
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
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)
