Essex Governor Services Ltd. (EGS) have just completed another successful overhaul job of 4 large steam valve actuators and Voith Way valves for steam turbines situated in a recycling plant.
This job was interesting for EGS engineers, as all 4 actuators were received in a stripped and broken down state, as the plant engineers had tried to examine the actuators themselves and in turn had severely damaged vital components on the 4 units.
After all components were chemically cleaned and stripped of any paint, they were then fully inspected to see the extent of the destruction. Major components were replaced as well as ‘O’ rings, piston rings, seals, receptacles and all consumable fasteners renewed.
EGS machine shop carried out bore honing to suit over sized pistons. Grinding and re-chroming piston stems to standard size. We also manufactured piston bearing/ seal housings.
Each steam valve actuator uses a Voith Way valve, so these were also overhauled. Once all units were carefully re-assembled and painted a vibrant blue colour, they were tested and delivered to the client.
With a lot of careful planning and production meetings, EGS were able to complete and turnaround this job in 4 weeks.
