RE | RAMechanical differential pressure regulators
Differential pressure regulators are used in particular when measuring gases in order to ensure constant flow rates in the case of fluctuating inlet or outlet pressure..
Minimum pressure levels are necessary to operate the regulators. Differential pressure regulators are not pressure reducing valves. The regulators are available in brass or stainless steel.

Example inlet pressure regulator  | Current flow : 1000 l/h air
| | Outlet pressure p2 constant (Atmosphere: 1.013 bar abs.)
| | The flow rate remains constant in the device in the case of fluctuating inlet pressure p1 greater than 1 bar. |
Example outlet pressure regulator | Current flow: 800 l/h air
| | Inlet pressure regulator p1 constant: 6 bar
| | The flow rate in the device is constant in the case of a fluctuating outlet pressure p2 of 0 to 5.5 bar. |
