TAILIEUCHUNG - NORSOK STANDARD MECHANICAL EQUIPMENT

Most cabinet actuator type governors also have a smaller auxiliary valve to control the gate position. Because of the relatively small ports of the auxiliary valve, the gates are moved slowly and can be positioned precisely. The auxiliary valve has no connection to the ball head, and therefore, no speed control. There is also no protection from the shutdown solenoids when on auxiliary control. A unit should never be left unattended when operating with the auxiliary valve. When operating with the auxiliary valve, the gates are moved by moving the gate limit. The gate position will follow the gate limit. | NORSOK STANDARD MECHANICAL EQUIPMENT R-001 Rev. 3 November 1997 Please note that whilst every effort has been made to ensure the accuracy of the NORSOK standards neither OLF nor TBL or any of their members will assume liability for any use thereof.
