Coaxial valves are ideal for directing aggressive gaseous (e.g. gas, biogas) and liquid media such as VE-Water. Due to their construction method, these valves can even be used with contaminated media or high viscosity, colloidal fluids. Directly controlled coaxial valves form NieRuf Industrial Valves work pressure-compensated, which means they shut off at 0,0 bar. Additionally, no pressure is required for power shift. Do you work with vacuum or counter-pressure? For our coaxial valves series CV01 and CV02 that is not a problem! The construction of the valves allows them to be used in areas of vacuum technology, in high-pressure systems or other appliances with counter-pressure.
