Pressure Regulators

Pressure regulators reduce a supply pressure to a lower outlet pressure and they maintain this outlet pressure regardless of inlet pressure fluctuations.  This reduction in pressure is the key characteristic of pressure regulators; outlet pressure is always at a pressure below the inlet pressure.

Operating Pressures:  The inlet and outlet pressures are important factors to consider before choosing the best regulator. Important questions to answer are: What is the range of fluctuation in the inlet pressure?  What is the required outlet pressure? What is the allowable variation in outlet pressure?

Flow Requirements:  What is the maximum flow rate that the application requires? How much does the flow rate vary?  Porting requirements are also an important consideration.
