Pressure regulators are used in pneumatic applications to set and keep the pressure level of a machine constant. For many applications, the pressure of compressors supplying compressed air in the range of 10...16 bar is too high, so it must be reduced using pressure regulators. Excessive pressure leads to higher wear in the application or unnecessarily high energy costs, a pressure level that is too low will not achieve the desired performance in terms of speed or force. The consequences are quality fluctuations and faulty results.
