Unwanted pressure increases in the system can damage machines and equipment, but also people in the vicinity. With a safety valve at the appropriate place you can reliably prevent damage.

How a safety valve works

When a pre-set set pressure is reached, the safety valve starts to open and reaches full blow-off capacity when 10% is exceeded. Once the pressure has returned to normal, the valve closes.

Compressed air is usually secured by freely blowing off valves. For hazardous media, e.g. steam, angle safety valves are used where the outflowing medium is conducted via pipes, e.g. into the open air or into collecting tanks.

Our product range includes safety valves with and without CE approval, in the connection sizes G 1/8 to G 2.

Safety valves with and without CE approval

A safety valve with CE approval has a fixed, non-variable set pressure. CE-approved safety valves are obligatory for machines and systems that are subject to a one-time or regular testing obligation (e.g. TÜV).

In the case of a safety valve without CE approval, the response pressure can again be set individually and changed if necessary. They can be used for test series and in areas where there is no risk of personal injury. However, they are not permitted for systems requiring testing.
