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: high-precision pressure control in the millibar range
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.
Unique selling points
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.
One valve series - countless applications
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.
Various configuration options
These millibar valves are available in brass or stainless steel. If they are not to be used as safety relief valves, the valves can optionally be fitted with filters in the inlet to extend the service life. A dirt strainer is also available for the outlet. Customers can also choose different elastomers for the seals, to suit the specific application. FDA-approved elastomers and components are also available.
The new standard for millibar valves
The models Ultravent 6 with 1/8" connection and Ultravent 15 with ½" connection are already available. The 25 and 50 variants will follow shortly. Whether as a safety valve, pressure control valve or vacuum breaker - the Ultravent series combines maximum performance with a compact design. With its innovative technology and versatility, WITT is setting a new standard in the control of gases in the low millibar range.
