LESER safety valves protect all processes in the brewery against impermissible overpressure.

LESER Clean Service safety valves are specially designed to meet the requirements of fermentation, storage, filtration and filling processes. They are characterized by:

Cleanability. Process integration. Conformity.

Thanks to their hygienic design, Clean Service safety valves are easy to clean. Contamination in the processes is avoided.

The Clean Service safety valves can be integrated into CIP/SIP processes, e.g. with pneumatic lifting. This enables reliable and efficient production.
Only components that comply with the relevant directives are used in LESER Clean Service safety valves . This makes it easier to prove the brewery's compliance with legal requirements.

The LESER HyTight design features 

• a low dead space inlet,
• a self-draining housing,
• manual or pneumatic lift-off,
• gap-free installation of the seals and
• surface quality optimised for the requirements.

This makes it easy to remove residues when installed. 

LESER safety valves can be easily and flexibly integrated into brewery processes. The manual or pneumatic lifting device enables the safety valve to be opened briefly during cleaning - there is no need to remove the safety valve. The lift indicator can be used to monitor whether the safety valve has opened. Thanks to the wide variety of connections, such as clamps, flanges or milk pipe fittings, the safety valve can be installed at any point in the system, whether storage tanks or filters.

LESER safety valves meet international standards for food and pharmaceuticals. Compliance ensures product safety by preventing the transfer of harmful components into food and pharmaceuticals.
To ensure the quality of the beer is right and no harmful substances can migrate, only suitable components are used in Clean Service safety valves. This is ensured by compliance with standards and guidelines, such as FDA or EU Directive 1935/2004. Global use is therefore guaranteed.
