Trapped pressure unloader from General Pumps. Brass housing with a yellow spring. Has a 21 GPM flow rate and and a maximum pressure rating of 2600 PSI.
The General Pump YU21235 Pressure Unloader regulates the maximum pressure of the system by varying the flow discharged by the bypass. Adjustment is made when a piston alters the position of a sphere inside the regulator. When the gun is opened, water flows through the valve which maintains the system pressure until the gun closes. The interruption of flow completely opens the bypass, allowing the discharge to flow at low pressure. This unloader has a maximum pressure of 2600 PSI.
