Series 355

The 355 flange safety valve series impresses with its consistent concept in terms of performance, function and design.

Why ductile iron?

The use of ductile cast iron as the body material results in a particularly cost-effective variant. This is particularly interesting for applications with heating water and steam and with lower corrosion resistance requirements.

Wide range of variants

This series can optionally be supplied with an open or closed spring cover. In addition, a wide range is available with elastomer or stainless steel bellows and both metallic and soft-sealing valve gaskets.
