Abstract

An enhanced mixing equipment system including a power supply, an actuatable valve, the actuatable valve connected via a line between the power supply and a storage vessel, an actuatable discharge/mixing valve attached to a portion of the storage vessel, the actuatable discharge/mixing valve connected via a line between the actuatable valve and a hose, a terminal end of the hose having a nozzle, a control input line connecting the power supply to a control valve positioned adjacent to the nozzle, and a control return line having a safety bleed positioned adjacent to the actuatable valve and connecting the control valve to the actuatable valve and the actuatable discharge/mixing valve such that any loss of pressure in the control return line results in closing the actuatable valve and the actuatable discharge/mixing valve as pressure is released through the safety bleed. With such an arrangement various configurations are possible which provide various redundancies in operator safety. These configurations may include, in one or more arrangements, an actuatable valve, an actuate able discharge/mixing valve, a safety bleed, and/or nozzle safety shutoff device.
