Series 492
atmospheric discharge safety valve

The 492 series safety valve with rotating outlet cover is used in high-pressure compressors and process systems as well as for protecting refuelling systems. It impresses with its compactness and design.

Thanks to its special technical design and construction, the 492 series covers an unrivalled pressure range of up to 1500 bar.

The valve is particularly suitable for hydrogen, whereby the high-performance materials used, such as PAI or PEEK, enable a very high level of tightness. This high level of tightness is maintained even after the valve has responded several times.

Temperatures: from -60°C to +200°C
Pressures: from 50 bar to 1.500 bar
