Spunding Valve, Tri Clamp 1.5", SS304
A spunding valve is used to control and maintain a set pressure inside a fermenter during fermentation or natural carbonation. It automatically releases excess pressure to prevent over-pressurization while allowing the brewer to achieve precise carbonation levels. This makes it suitable for both homebrewing and professional brewery applications.
The valve mounts directly onto any 1.5" Tri Clamp port and provides an adjustable and sanitary pressure-control solution for closed-loop fermentation.
