Stationary KN 039-291 IMPCO Secondary Gas Regulator
How does a low pressure regulator work?
A pressure regulator reduces a supply (or inlet) pressure to a lower outlet pressure and works to maintain this outlet pressure, despite fluctuations in the inlet pressure. The reduction of the inlet pressure to a lower outlet pressure is the fundamental characteristics of pressure regulators.
Model KN 039-291 is a secondary regulator. It is suitable for use with low pressure, Natural Gas and LPG Vapor fuels. This regulator is typically used in service applications up to 30 kW.
We develop and manufactures dedicated fuel systems for industrial engines using clean burning fuels such as LPG, Propane, Natural Gas or Biogas. Our engineering focus is on optimal system integration with best possible vehicle performance and exhaust gas emissions.
