NLB’s 286 series hand lances and foot control valves are designed for maximum operator protection and productivity. A patented trigger/pedal design (U.S. patent no. 5,636,789) lets you dump pressure immediately by simply pushing the trigger/pedal forward. One of the most popular features of these tools is a unique quick-change cartridge that you can replace in the field in less than 60 seconds. It is available in most models, with operating pressures ranging from 10,000 psi (690 bar) to 40,000 psi (2,760 bar).
