Hello
we are using some Sitindustrie Ball valves (full bore and reduce bore) size 4''#1500RF.
The actuators are very old and we need to replace new actuator.
However, we don't keep any document or drawing of Topwork of the Sitindustrie ball valve.( it helps fabricate the exactly mounting kit and adaptor when exchange the actuator)
we have tried to ask the factory but get no support.
if anybody has the documment, please share.

Thank you in advance!
