SS304 Sanitary Spunding Valve with Diaphragm Gauge (1.5" Tri-Clamp, 0-2.2 Bar)

Technical Specifications

Key Features & Benefits:

• Premium Material: Premium made of 304 or 316L stainless steel for superior corrosion resistance and maximum hygienic protection.

• Adjustable Pressure Control: Equipped with a calibrated adjustable scale, allowing operators to set precise pressure release points easily.

• Sanitary Tri-Clamp Connection: Standard tri-clamp ends ensure quick installation, easy maintenance, and full compatibility with standard sanitary fluid systems.

• Applications: Ideal for brewery fermentation tanks, bright beer tanks, food processing lines, and pharmaceutical vessels.

What is the difference between a Spunding Valve and a PRV (Pressure Relief Valve)?

• Spunding Valve (Process Control)

• A Spunding Valve is a highly adjustable process tool used by brewers to actively hold a specific pressure (e.g., 15 PSI) inside the tank for natural carbonation. It gently bleeds off excess CO2 produced by the yeast. However, it can become clogged by sticky yeast krausen during vigorous fermentation.

• PRV (Emergency Safety)

• A fixed-pressure PRV is an emergency safety device. It is not meant to be adjusted or used for carbonation. It is a fail-safe that strictly prevents the tank from exploding if the Spunding Valve gets clogged. You must never remove your PRV to install a spunding valve.

Why does this spunding valve use a "Diaphragm" pressure gauge?

1. Sanitary Design: Standard threaded pressure gauges have tiny internal tubes (Bourdon tubes) where beer and bacteria can get permanently trapped. A diaphragm gauge features a flat, flexible stainless steel membrane that separates the gauge internals from the beer, eliminating dead legs.

2. Easy Cleaning: Because the fluid only touches the flat diaphragm, the entire valve and gauge assembly can be thoroughly cleaned and sanitized using standard CIP (Clean-In-Place) procedures without risking contamination.
