Designed for high-pressure trimming applications in the pulp and paper industry, BEX WT Series nozzles contain a synthetic ruby insert in the housing in order to provide more wear resistance than comparable stainless steel nozzles. They produce a steady laminar stream of liquid at pressures up to 2,000 PSI. The company says an adjustable TeflonĀ® shield protects the orifice from loose strands of fiber that could otherwise plug ?the orifice.
