The Fairchild 2800 is designed for applications requiring rapid changes in set pressure. This precision device provides excellent sensitivity with high forward and reverse flows. The plunger design allows more rapid set point adjustment over the pressure range of the unit than conventional control knob models.
The Fairchild 2800 is recommended for use in a variety of applications where rapid pressure changes are required, including control stations and test panels, and in construction machinery and industrial or oil rig control equipment.
