WITT presents its revolutionary ULTRAVENT series – innovative millibar valves for precise pressure control from 5 to 500 mbar. These highly versatile valves reliably regulate both negative and positive pressure and ensure maximum control and safety in systems, vessels, and production processes.
ULTRAVENT valves are true all-rounders. They function as safety relief valves, control valves, vacuum breakers, overflow valves, pressure relief valves, tank breather valves, venting valves, and even as an alternative to bursting discs. As a purely mechanical solution, the spring-loaded components are particularly uncomplicated and at the same time highly precise and reliable. If the set pressure is exceeded, the precision valves open and automatically close tightly again after pressure equalisation. The model range has been tested over 100,000 cycles to ensure maximum reliability.
ULTRAVENT is the only valve of this type with TÜV Type Approval as a safety valve in the pressure range 100 to 500 mbar, per DIN EN ISO 4126-1. Its flow-optimised design allows very high flow rates when required, despite its compact size. Thanks to its high-quality elastomer seals, the valves also feature extremely low leak rates. The opening pressure set at the factory is witnessed and certified by the TÜV and an individual TÜV certificate is supplied.
The ULTRAVENT family is designed for a wide range of industrial gas applications, making the smallest pressure ranges manageable and reliably protecting sensitive processes and systems. The valves can even be used in high temperature applications.
