DIN Food Grade Safety Valves Stainless Steel 304 Union Type Spunding Valve with Thread Pressure Gauge 2Bar 1inch Spunding Valve

SS304 DIN Union Spunding Valve with Pressure Gauge (0-2.5 Bar)

Engineered for precise pressure management in European-standard brewing systems, the Aomite DIN Union Spunding Valve guarantees accurate carbonation and reliable overpressure protection for commercial fermenters.

Unlike standard clamped valves, this model features a robust DIN 11851 Union (threaded nut) connection for exceptionally secure integration into your existing sanitary pipework. Crafted from premium 304 stainless steel, it comes fully assembled with an in-line sanitary diaphragm pressure gauge. This allows brewmasters to visually monitor and fine-tune blow-off settings from 0 to 35 psi (0 - 2.5 BAR). The transparent polycarbonate cup can act as a liquid airlock, ensuring oxygen-free, clean, and safe fermentation environments. Available in sizes from 1 inch to 2 inches for bulk OEM supply.

DIN Union vs. Tri-Clamp Spunding Valve: Which connection to choose?

Feature	DIN Union Type (This Product)	Tri-Clamp Type
Connection Method	Secured via a threaded slotted nut and a C-spanner wrench.	Secured via a hinged clamp and a wingnut.
Pressure Handling	Extremely robust. The threaded nut provides superior resistance to accidental bumps or high-pressure spikes without loosening.	Excellent for quick tear-downs, but the clamp hinge can be slightly more vulnerable to physical impact.
Regional Standard	Standard in European (German) brewing and dairy equipment.	Standard in North American and general global sanitary systems.

Why does this valve use an "in-line diaphragm pressure gauge" instead of a standard gauge?

Sanitary Diaphragm Design
A standard bourdon-tube gauge has a hollow tube inside that can allow sticky yeast or beer foam to enter, causing bacterial contamination that is impossible to clean. Our sanitary diaphragm gauge uses a flush stainless-steel membrane to isolate the gauge internals from the fermentation gas. This ensures the valve remains 100% CIP-cleanable while delivering highly accurate pressure readings up to 2.5 Bar.
