Here is how it works

Breather Valve Functionality Similar to a pressure vacuum relief valve the breather valve component of this device opens to relieve excess pressure or vacuum inside the tank It prevents overpressure or vacuum conditions that could potentially lead to tank rupture or collapse
Flame Arrester The flame arrester is a critical safety feature designed to prevent the propagation of flames into the storage tank or vessel It consists of a mesh or perforated metal plate with narrow passages that disrupt the flame front causing it to extinguish before it can enter the tank and ignite the contents.

FAQ's of Breather valve cum Flame Arrester (Pipe Away):

Q: How does the Pipe Away Breather Valve cum Flame Arrester function in hazardous storage applications?

A: This device provides robust pressure and vacuum relief for storage tanks while incorporating a stainless steel flame arrester element to prevent flame propagation from external ignition sources. Its direct-acting mechanism ensures rapid response to pressure changes, offering dual protection against overpressure and explosion risks in chemical, petrochemical, and pharmaceutical industries.

Q: What makes this breather valve suitable for corrosive or outdoor environments?

A: The valve uses corrosion-resistant materials such as stainless steel, cast iron, or aluminum, and is protected by an epoxy/polyurethane coating. Combined with a weather hood and various sealing options, the unit withstands aggressive chemicals, weather, and demanding service conditions, making it ideal for outdoor or corrosive settings.

Q: When and where should this breather valve be installed?

A: This valve is designed for installation on vertical pipelines of storage tanks or vessels handling air, vapours, or combustible gases in locations where safe venting to a remote area (pipe away) is needed. Typical applications include chemical plants, refineries, and pharma industries requiring explosion protection and proper tank breathing.

Q: What is the maintenance process for the breather valve cum flame arrester?

A: Routine maintenance is made simple as the valve allows for inspection and servicing of internal parts without line removal. Periodic checks involve examining the flame arrester element, seals, and vent ports for cleanliness and integrity, ensuring safe and efficient operation over time.

Q: What are the available sizes and connection standards for this product?

A: The valve supports end connections from 2 to 12 inches (DN50 to DN300) and can be supplied with flanged ends as per ANSI or DIN standards. Custom sizes and connections are also available upon request to suit specific installation needs.

Q: Which benefits does the integral flame arrester offer compared to separate installations?

A: By combining the flame arrester and breather valve into a single, compact unit, installation complexity and space requirements are reduced. This integrated solution improves safety, minimizes pressure drop, and offers cost advantages while ensuring both pressure/vacuum relief and flame protection.
