Premium 304 Stainless Steel Dual-Action Breather Valve – Automatic Pressure & Vacuum Protection for Sanitary Tanks
Engineered for critical hygiene-sensitive environments, this sanitary pressure vacuum relief valve delivers automatic dual-direction protection for sealed tanks and vessels in food processing, pharmaceutical manufacturing, brewery fermentation, and dairy operations. As a self-acting breather valve, it safeguards equipment from both dangerous overpressure and vacuum collapse during filling, emptying, CIP cleaning, and temperature fluctuations.
✅ Sanitary Material & Construction
304 stainless steel body: Corrosion-resistant, impact-resistant, and compliant with food-grade sanitary standards
Mirror-polished finish: Inner surface Ra ≤0.8μm prevents bacterial adhesion and product sticking
Precision CNC machining: Manufactured to 3A, DIN, and ISO公差 standards for reliable sealing performance
Dual-Action Protection Mechanism
Pressure relief function: When tank pressure exceeds the set threshold (field-adjustable 0.5–2 bar / 7.3–29 psi), the valve automatically opens to vent excess pressure
Vacuum break function: When negative pressure (vacuum) develops inside the tank, the internal piston automatically opens to draw in air, preventing tank deformation or collapse
Spring-loaded automatic operation: Ensures consistent, repeatable, and maintenance-free performance
Tri-Clamp Connection & Versatility
Standard Tri-Clamp fitting: Tool-free installation and removal for 1.5″ to 4″ sanitary ports
Interchangeable with industry standards: Compatible with DIN, SMS, and 3A sanitary piping systems
Multiple size options: Available from DN15 to DN100 (1″ to 4″) to suit various tank capacities
Multi-Industry Applications
Brewery & beverage: Fermenters, brite tanks, and Unitanks – prevents vacuum collapse during cold crashing or draining
Food processing: Pasteurization lines, storage tanks, and CIP systems
Pharmaceutical & biotech: Sterile vessels, bioreactors, and high-purity water systems
Chemical processing: Corrosive fluid storage and reactors (316L optional)
⚡ Operational Benefits
