Maximum reliability under extreme pressure

Independent of nominal size, two-way block-body ball valves in the HBV series from Stauff are highly suitable for use in the extreme pressure range up to 800 bar, thanks to massive construction and the use of high-quality materials. The extreme seal stresses caused by high pressure loads are captured by special chambering. In addition, this special protective system prevents erosion and rapid wear of the sealing rings. The shut-off valves are designed for direct pipeline installation and are available with optional connections for cutting ring connections of the heavy series according to DIN 2353 / ISO 8434–1 or NPT internal threads. The surfaces of the standard ball-valve housing in the HBV series are produced without chromium(VI), giving them maximum protection from corrosion. More than 300 h of resistance to red rust by the zinc/iron coating in the salt-spray chamber outperforms the usual chromating and phosphating on the market many times over. Furthermore, the surface meets the specifications of current EU directives with respect to the use of hazardous heavy metals.
