- 17 - ABSTRACT A pilot valve (40) for a control valve (14) has a separate auxiliary source of high pressure fluid (106) for the operation of the pilot valve (40). The dome chamber (36) of the control valve (14), the inlet fluid chamber (72), and the intermediate fluid chamber (104) are exposed only to the auxiliary source of fluid (106). Thus, process fluid from the sensing line (62) does not contaminate the spool valve (76) or the dome chamber (36).
