Many applications require mechanical pressure regulators, which are able to keep a constant supply pressure exactly and long-time stable. The M10 precision pressure regulator from Fairchild with control ranges from 0 up to 150 mbar or 0 up to 28 bar satisfies highest requirements.

The setting of the control pressure is transmitted by a spring-diaphragm-system to the valve controlling the flow. There is a balance of forces between the spring-diaphragm-system and the opposing output pressure, which keeps the output pressure nearly constant even with major changes. To prevent persistence due to friction, a small quantity of air is continuously blown out by a release valve.
