Lubrication
General
Trunnion bronze bushings receive a significant amount of water lubrication from the media itself. For those ball
valves equipped with grease fitting lubrication points on the body assembly
– each lubrication point should be
greased with a hand-pump gun (
Caution!
do not use air-operated grease guns). Use one of the approved
lubricants from Table A.

Lubricate twice annually (more often if valve is operated frequently or in harsh service conditions) using one of
the approved lubricants from Table A. Use approximately 4 ounces of grease per bushing per re-lubrication
event. Check with the factory in the event that a special application prevents the use of the approved
lubricants.

Lubricate twice annually (more often if valve is operated frequently) or any time the cover is removed. Wipe out
old lubricant and replace with new lubricant using one of the lubricants from Table A. Spread lubricant on the
crosshead side members; crosshead guides, leadscrews, all rotating and sliding areas, bearings, exposed
steel or cast iron machined parts, etc. See Table B for recommended amount of lubricant for the various size
