A pressurized fluid discharge gun is used to spray high pressure fluid against various types of surfaces for cleaning purposes. To operate the gun two handles, each with a separate trigger, must be firmly held by the operator. When both triggers are compressed firmly towards the handle, highly pressurized fluid exits the gun. If either one of the triggers is released then the fluid is dumped to a low pressure discharge, i.e. high pressure fluid is not permitted to exit the gun. The gun has a high pressure pipe and a low pressure pipe connected to a main body. A valve assembly, located in the main body, controls whether the fluid from the inlet goes to the high pressure pipe or the low pressure pipe. The valve assembly has a high pressure path and a low pressure path interconnected by two passages. Two pin valves, each controlled by one of the triggers, block the two passages when the triggers are compressed resulting in high pressure fluid flow. When either trigger is released, the pin valve moves causing its respective passage to open resulting in low pressure fluid flow.
