Breather Valve (Pressure Vacuum Relief Valve)
Manufacturer of PVRV Breather Valves for Process & Pipeline Applications
Hyperr Valves Pvt Ltd is a leading manufacturers, supplier and exporter of Breather Valve (Pressure Vacuum Relief Valve). Our Breather Valve (PVRV) is an essential tank protection device designed to maintain internal tank pressure within safe limits during normal operation. It functions by “breathing” in to relieve vacuum during pump-out or thermal cooling, and “breathing” out to relieve overpressure during tank filling or thermal expansion. This dual-action mechanism prevents catastrophic tank damage—such as buckling (implosion) or rupture—while significantly minimizing valuable product loss and fugitive emissions.
Engineered to meet API 2000 and ISO 28300 standards, our PVRVs utilize precision-machined pallets and seats to ensure superior sealing. We use SolidWorks simulations to optimize the flow profile, ensuring the valve achieves full lift at low overpressures for maximum efficiency.
Key Features:
- Dual Protection: A single unit manages both Over-Pressure (out-breathing) and Vacuum (in-breathing) risks.
- Vapor Conservation: Remains sealed until set pressure is reached, drastically reducing evaporation losses and odors.
- Precision Sealing: Air-cushion pallet design and soft-seating options (Viton, etc.) ensure minimal leakage and resist freezing.
- Gravity or Spring Loaded: Available in weight-loaded designs for low settings or spring-loaded for higher pressure applications.
- Standard Compliance: Flow capacities certified to API 2000, ensuring safe venting rates for storage tanks.
Applications:
- API 650 Storage Tanks
- Petrochemical Terminals
- Solvent Storage
- Food & Beverage Fermentation Tanks
