Fixed-flow Chief™ nozzles efficiently deliver a constant gallonage from straight stream to full fog. The simple, rugged design makes the Chief™ easy to use and train with and reliable in tough situations. Superior hydraulics, due to a fully machined waterway, result in excellent stream quality and reach. This nozzle can switch between straight and fog stream patterns and can flush without shut-off. The constant flow feature maintains the same flow rate throughout the stream pattern selection, making it ideal for use with foam eductors and for foam application. The two-piece, floating stem is designed to prevent damage to the stem head if the nozzle is dropped on the tip. The stem head can also be easily replaced in the field, thereby allowing the Chief™ nozzle to be retrofitted to optional flows and pressures if required.
