NLB water blasting units use positive displacement reciprocating pumps. This means that when they are on, they are constantly pumping water. Since shut-off-style lances and foot controls have no built-in means of dumping pressure, the safest way to use them is with an unloader valve. These are activated when an operator releases the trigger of the lance. This essentially shuts off the outlet for the water. When this happens, the unloader valve opens and dumps the water.
In automated applications, unloader valves can also be used to divert water back to the tank when the flow is shut off at the work site. NLB offers 25 gpm (UL-452) and 50 gpm (UL-904) models, both constructed of stainless steel for long life. Repair kits are available.
