Stainless Steel 1-1/2 Inch Vacuum Relief Valve

Use this sanitary pressure and vacuum relief valve to help ensure pressure and vacuum do not exceed the design tolerance of the 3-in-1 and 4-in-1 conical fermenters. Factory set to release pressure and break a vacuum.

Corrosion-Resistant, Even in Tough Environments

304 stainless steel isn’t just “stainless”—it’s built for the worst:

• Resists acids, brines, and chlorides: Perfect for chemical plants, seafood processing, or coastal facilities (no pitting, no rust).
• Withstands high temps: Rated for continuous use up to 450°F (232°C) and short spikes to 600°F (315°C) (no warping under steam).
• Easy to clean: Smooth, non-porous surface prevents buildup (ideal for food-grade or pharmaceutical systems).

Precision Engineering for Instant Response

Vacuum spikes happen in seconds—your valve needs to react faster. Eagle’s design:

• Spring-loaded diaphragm: Opens at a precise vacuum level (adjustable from 6-12 in. H2O) to prevent system collapse.
• Large 1-1/2 inch port: Handles high flow rates (up to 300 SCFM) to equalize pressure before damage occurs.
• Leak-proof seal: Silicone O-ring ensures zero air loss during normal operation (no wasted energy, no false alarms).
