Pressure relief valves are used on process vessels to maintain a fixed pressure within the tank, with any excess gasses produced during the process to be safely vented. A sub-set of the gas pressure relief valve is called a bunging valve. This is supplied with a glass shield around the valve which can be filled with water to provide visual feedback that the tank is venting. These are commonly used in brewing applications to see how active the fermentation process is.
All valves produced by Guth are tested on completion to ensure that valves supplied work within their designed parameters.
Valve features include:
• Variable pressure control
• Manual override
• 0.5-8.0 bar pressure range (0.2-3.2 bar for bunging valve)*
• Optional cleaning hood
• Can be supplied in a pressure regulation array (Can include; Anti-vacuum**, pressure level indicator, CIP integration & pressure relief)
Pressure Relief Safety valves available in sizes DN20 - DN65
Bunging valves available in sizes DN25 - DN65
**An anti-vacuum valve is used on a pressurised vessel to allow gas into the unit while the tank is emptied, while maintaining a secure pressure seal during operation. This can be supplied as a standalone item, or part of a pressure regulation array which can be installed onto a unit.
