NLB’s dry shut-off guns are used in conjunction with an unloader valve to allow the operator to completely stop the flow of water at the job site. Traditional dump style lances continue to output water even when the system is not pressurized. This water exits the dump port at low pressure. A system utilizing an NSG lance and an unloader valve allows the operator to dump the water at a remote site, eliminating excess water at job sites that are water sensitive.
There are three models available. Please refer to the following chart for specific details on each. All three can easily be rebuilt with the referenced rebuild kit.
