Witt-Gasetechnik launched its smallest relief valve, the AV319. Complementing the AV619 and AV919 low set pressure models, the AV319 is just 42mm long and just 14mm in diameter – and it fits just about anywhere. Accurately and reliably protecting your low-pressure gas systems from overpressure makes the AV319 your ideal last line of defence. Its accuracy also helps protect against process control excursions that affect production line quality. Its set pressure can be adjusted accurately and precisely to set points between 10mbar and 80mbar. In addition, the especially tight seal ensured by its spring-loaded valve and elastomer seal altogether puts the AV319 in a class of its own.
With 100 % testing and individual test certificate from TÜV – Germany’s national technical inspection agency – the AV319 is ideal for technical gases between -30°C and 100°C and comes in brass or stainless steel.
