B&W / Sulzer Fuel Valve Overhaul

We have overhaul & testing facilities for all Wartsila Sulzer RTA & B&W MC, GB(E) and GF(CA) fuel valves.

Our workshop is equipped with the latest IOP Marine test rig as recommended & approved by MAN & Wartsila for testing their fuel valves.

The test rig features IOP’s “Safe Test Technology”: Developed in association with MAN, this electronic control system allows the correct & safe testing of B&W slide valve injectors without the risk of damage that can be caused by traditional testers.

For Wartsila Sulzer RTA fuel valves the rig also includes a hydraulic spanner to enable easier dismantling and to allow the nozzle retaining nuts to be accurately re-torqued to the required specification.


Spindle Guide / Needle & Guide Reconditioning

As well as complete injector overhaul, we also recondition spindle & guide assemblies, non-return valves and circulation valves for B&W and Sulzer injectors, extending the service life of these costly components.
