Portable Grinding and Lapping Machines
Reduce your maintenance costs
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 valve grinding and lapping machines for flat seats (Valva)
Portable machines for grinding and lapping of sealing faces in valves, valve disks, flanges etc. An impressive concept of simple operation, wear-resistant tools, good price/performance ratio, high profitability and efficiency.
Work range:
Power supply:
DN 8 – 1600 mm (¼“– 64“)
electric 230 / 110 V, 50/60 Hz or pneumatic 6-7 bar

Portable valve grinding machines (SL / HSL / SLA)
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.
