The main application for the CVS 670 Series panel mounted loading regulator assemblies is in the manual control of pressure to diaphragm control valves. They are also used as remote pressure loaders for pressure-balanced gas regulators, and the control of gas pressure to burners in refinery tube stills, power plants, and other process furnaces.
CVS Series 670 regulators control supply pressure to diaphragm control valves or gas regulators, and are set manually. Instrument and manual loading pressures are read from the pressure gauges of the regulator.
Pressure to the valve can be adjusted using the regulator handwheel (clockwise to increase supply pressure and counterclockwise to decrease supply pressure).
