as well as surface lapping machines, mobile workshops, consumables, workshops, workshop planning etc.
If you are active in repair and maintenance of valves, you require a strong partner who can help to optimise your efforts.
EFCO can offer you the most up-to-date and advanced technical solutions for valves, repair and production. It is their aim to offer you unique products, support and service.
Portable grinding and lapping machines
Flat sealing faces guarantee perfect valve seals. If this area is damaged, the repair is quick and uncomplicated with the EFCO grinding and lapping machines which can be used on site. Thanks to this portable technology it is not necessary to remove the valve from the plant which contributes to an effective reduction in maintenance costs and thus the costs of outages.

| Portable high-speed valve grinding machine (HSS) | |
 |
Portable high-speed valve grinding machine is designed in particular for the grinding of old sealing faces and face grinding of new sealing faces. Work range: DN 80 – 600 mm (3 ¼" – 24") |
Portable turning machines
Due to the constantly rising pressure on the costs of industrial maintenance, the demands made on the machines and tools required also increase. It is frequently difficult or even impossible to dismantle sealing faces, flanges and bores on valves, heat exchangers, boilers etc. for remachining in a workshop. The portable EFCO turning machines have been developed specifically for this application. They can be used almost everywhere and in every installation position.
| Portable facing machines for flanges (TDF) | |
 |
When seals are replaced, it is frequently unavoidable that the sealing faces themselves have to be remachined due to damage from heat or aggressive media. EFCO portable flange facing machines with external clamping are suitable for this type of work in pipelines, on large valves, pumps, chemical plant, turbine housings, heat exchangers etc. Simple installation, low weight and flat design of the machines make use of these machines possible on site in almost any position. The required roughness of the sealing faces can be obtained due to variable feeds during machining. Inclined faces can be machined using additional tools.
Work range: DN 0 – 3200 mm (0" – 126") |
| Portable turning machines for sealing faces, flanges and holes (TD) | |
 |
The EFCO-TDs are portable turning machines for the precise machining of holes and sealing faces in valves, cylinders, pumps, turbine casings etc. These machines are suitable for use on site and in the workshop, in power stations, for valve service, for chemical and petrochemical plants, for shipyards and oil fields. All controls are easily accessible and enable simple and safe control of the equipment. These machines can be equipped optionally with a CNC control to make more complex work sequences possible.
Work range: up to DN 900 mm (up to 36") |
| Portable CNC turning machines for sealing faces, flanges and holes (TD-2T / TD-3E) | |
 |
Both versions consist of portable CNC turning machines with external clamping and controlled axes. A special feature is the machining of radii and cones up to DN 1500 (60"). All functions can be used manually via a manual operating panel or run as a cycle.
Work range: up to DN 1500 mm (up to 60'') |
Stationary machines
The stationary EFCO machines are designed for grinding, lapping and turning in your workshop. These machines have been developed specially for the machining of valves based on ergonomic and economic principles. The design placed emphasis on fast set-up and simple operation.
