Baker Hughes Safety Relief Valve 1982 Series

A 12-month maintenance interval is recommended for general service conditions. For severe service applications, a 3 to 6 month inspection and testing interim may be more appropriate. The specific plant’s operating and service history will better determine this frequency. Baker Hughes encourages preventive maintenance. Occasionally, remachining may be necessary to extend the service life of a valve. Keep all parts for each valve separated to ensure replacement in the same valve.

DANGER: Insure there is no pressure in the inlet of the valve before attempting to remove it from the piping system.

Note: For maintenance questions not covered in this manual, please contact your local Green Tag Center (GTC).;
