ABSTRACT:
A rotary control valve which is actuated by a steel bellows mechanism for use in a gas chromatograph. The steel bellows mechanism changes the valve positions as required by the gas chromatograph operation. An improved spring design provides an even pressure to the disc rotating against the valve body as well as allowing this pressure to be varied. Use of steel bellows and the proper materials for construction of the control valve will allow complete installation in the oven of a gas chromatograph for operation at a maximum temperature of 600.degree. F.
