With the new ULTRAVENT 6 safety valve, even the smallest pressure increases from 5 mbar can be controlled in gas systems. Based on DIN EN ISO 4126-1, the extremely compact valve from WITT offers unprecedented blow-off performance and has excellent opening and closing behavior that is reproducible even in the millibar range. This means that sensitive systems, containers and production processes are reliably protected against overpressure.
Model 6 is the first and smallest valve in the new Witt ULTRAVENT product range. It is a direct-acting, spring-loaded valve that opens and blows off when the opening pressure is exceeded. After pressure equalization, it closes automatically. As a purely mechanical solution, the safety valve is less complicated, more economical and more reliable than more complex combinations of pressure transmitter and solenoid valve. The extremely high reliability of the new valve has been proven in tests with over 100,000 cycles.
