The Pressure Regulating System Unloader nitrogen-regulated pressure unloader valve for multiple guns from Gardner Denver Waterjetting Systems uses a nitrogen bladder to maintain at least 98 percent pressure to allow multiple operators unrestricted freedom and safety, while reducing shock to operators when guns are actuated. It absorbs the shock from the energy in a rubber bladder inflated with a cushion of high-pressure nitrogen able to safely actuate water pressure up to 20,000 psi. 281/448-5800;
