Safety Relief Valves from WITT - AV Series

Millibar-accurate and robust

Just as the flap of a butterfly's wings can trigger a tornado, perhaps a mere minimal change in pressure in a production process will unleash an unwanted effect. Do not allow this to happen! Protect your process against the slightest overpressure!

We at WITT design and manufacture small components with a big effect. Our AV safety relief valves offer reliable protection against minimal overpressures and make even the smallest pressure changes controllable.

Of course, they come with a TÜV setting certificate that proves the individually set opening pressure for each individual valve. Please do not hesitate to contact us about individual safety relief valves and special solutions.
