The valves with coaxial design are designed completely pressure balanced. The pending medium pressure has almost no influence on the switching behavior. The switching capacity remains constant and the valves switch safely – regardless of whether under vacuum, low or high pressure. Only the seal friction at the highest pressures limits the pressure levels.

Application The coaxial valves are particularly suitable for lubricants in mechanical and plant engineering. Other possible uses can be found in vacuum and gas technology, in test bench construction, in ship and rail engines and in filling and dosing technology. By means of suitable seals, both gaseous and liquid, dirty or gelatinous media can be used, e.g. oils, emulsions, and coolants and lubricants.
