pressure gauge of oil pump at oil field, south of SK, Canada.
Pressure regulator valve that controls the pressure of a fluid or gas in factory supply
An analog pressure gauge that installed on the water pumping machine pipeline, using to measuring the pressure during operate. Industrial equipment object photo.
Pressure regulators reduce a supply (or inlet) pressure to a lower outlet pressure and work to maintain this outlet pressure despite fluctuations in the inlet pressure. The reduction of the inlet pressure to a lower outlet pressure is the key characteristic of pressure regulators.
