I am looking for a parts distributor for a Hagen Control valve on a Fuel Oil system on a old ship.
It appears that Westinghouse had owned this company at one time I need some parts for a ship we are working on. I can't find Hagan Controls parts I am looking for a distributor for Hagan Controls Corp. from Pittsburgh PA
Hagan Controls was indeed owned by Westinghouse, and was taken over by Siemens when they purchased Westinghouse. So, you might try your luck with Siemens. But I think you may also need to consider replacing the control valve in case you can't get the necessary parts. You didn't say what type of parts you are looking for (valve internals, actuator, positioner).
Try Emerson/ Rosemount. See if you can find a manual online with the part numbers and pictures if you have the model number of the valve. I believe they bought Hagan. It's best to call then send them a picture for what you need. We recently bought parts for a Hagan Power poisoner from them so I know they have piston operators. You may need to be persistent in order to get to the right branch of their company.
Hagan was purchased by Rosemount which is owned by Emerson. Parts if available would be ordered through one of their Regional Rep's. Before they were sold they went by the name Combustion Control Division and Computer and Instrumentation Division both of Westinghouse. Plant was located in Orrville Ohio.
