Bellow valve: Bellows sealed globe valve
The bellows-sealed shut-off valve ensures a tight sealing, which effectively prevents leakage. This is particularly critical in industries such as power generation, petrochemical plants, water & wastewater management, chemicals, pharmaceuticals, food processing and general industrial applications where safety and purity are paramount. In addition, the bellows seal effectively prevents emissions of hazardous or environmentally harmful media.
The bellow valve type VG234 is an excellent choice for demanding industrial applications. It is characterised by its high reliability and durability and is available in various nominal connection sizes from DN15 to DN250. This shut-off valve with bellows is available from stock in ductile iron (GGG40), grey cast iron (GG25) and cast steel (1.0619), in flange connections PN10, PN16, PN25 and PN40. Constructed with a robust X6CrNiMoTi17-12-2 stainless-steel bellows and graphite packing, this industry standard bellow sealed valve offers an exceptional service life. The globe valve type VG234 is TA-luft certified. Due to its excellent manufacturing quality, this shut-off globe valve can be used to control many industrial liquids, gases or steam.
Choose our bellows-sealed valve type VG234 for efficiency, safety and a long service life of your system.
