Automatic pressure controller

Operation pressure of the FPS system is important to keep stable and correctly adjusted. In a normal FPS system this is achieved with a regulator on the valve unit. If there is a need to adjust the system dilution ratio frequently, the pressurized air supply fluctuates or the valve unit needs to be situated in a hard to reach place, use of the regulator may be troublesome. For this reason, Dekati has developed an automatic pressure regulator, which keeps the operation pressure always nominal without adjustment by user. The pressure regulator can be applied for FPS units manufactured after 05/2005 without modification and to all version 2.0 units with a small modification possible to carry out during normal instrument service at Dekati.
