Portable machines for grinding and lapping of sealing faces in gate valves and non-return valves, gates and flanges. Optionally, these machines can be fitted with a digital rocker for contact pressure. This patented unit guarantees reproducibility and absolutely flat sealing faces. In addition, our valve grinding machines can be fitted with a swing-check adapter to enable machining of sealing faces on non-return valves with a large inclination. Hard seats can be machined with our portable high-speed valve grinding machine with driven spindles. This makes extremely fast and effective machining possible. This option can be retrofitted (SLA) on existing machines or can be supplied as a complete system. Fast setup and removal of the machines is guaranteed by means of a specially developed clamping block. pdf datasheet

The KS stationary grinding machines for valve and machine components can be used on site or in the workshop. They are suitable for face grinding gates, valve seats and other machine components. The aluminum grinding plate is fitted with self-adhesive abrasive disks. A fixed stop provides improved guiding of the work piece. pdf datasheet

EFCO surface lapping machines are excellent for lapping individual or series components, face seals, valve seats, gates, etc.. Worn components, such as valve seats, mechanical shaft seals, disks, etc., can be re-lapped in repair workshops and at refurbishment companies. Automatic and finely adjustable lapping compound feed as well as freely adjustable lapping table speed guarantee high quality lapping results.

Stationary ball valve lapping machine for the simultaneous finishing of the ball and 2 metallic sealing rings. For small and medium-sized ball workpieces with diameters of up to 300 mm.

The EFCO TDs are portable lathes for precision machining of bores and sealing surfaces in valves, cylinders, pumps, turbine housings, etc. These machines are suitable for use on site and in the workshop, in power stations, for valve servicing, for chemical and petrochemical facilities, in steel construction, in shipyards and in oilfields. pdf datasheet

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. Our 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.

The ASM is a portable lathe for cutting out welded seat rings in valves. It is suitable for use on site and in the workshop, in nuclear power plants, in conventional power plants, for valve service, for the chemical and petrochemical industry, in steel construction in shipyards and oil fields.

With the portable CNC controlled lathes we achieve a completely new quality standard in flange and valve seat machining. Because of the pre-programmed processing cycles, the TD-2.02 NC special machine is ready for immediate use, and can be operated after just a small amount of instruction and no previous CNC programming knowledge. Machining options with the EFCO NC lathes. Of course, you can also supplement the program package with your own CNC programs.

PDM machines are designed for the axial machining and facing of fitting housings (gate valves, valves, check valves), pumps and similar rotationally symmetrical components. They have infinitely variable speed control and axial and radial feeds (Z and X axis) with infinitely variable control that make it possible to move both axes simultaneously at different speeds. They are equipped with CNC programs that are specially tailored to turning requirements. During program development, special attention was paid to making operation as simple as possible. Operation takes place using a portable electronic control unit.

Stationary precision turning machines, CNC-controlled. The optimum solution for complete machining of valves, for general overhaul and also for use in production. The machines of this range have precision inclined tables (±12°, accuracy ±10“) and have been optimised for more efficient machining of valves. A particular advantage for the machining of gate valve sealing faces is the clamping. It is possible to machine both sealing faces with only one clamping by adjusting the angle at the swivel table. The symmetry of both sealing faces is thus ensured. Due to the flexible design, SPM machines can also be used for other machining tasks. They are equipped with CNC programs that are specially tailored to turning requirements. During program development, special attention was paid to making operation as simple as possible. Operation takes place using a portable electronic control unit.

Due to its flat design and the low weight, the portable, ID-mounted TDFI facing machine with flanges is ideal for applications in areas with limited working space.
