51 Radial Spray Valve 782RA Unique design uses a precision air motor and Low Volume Low Pressure technology to apply a uniform coating of lubricants, primers and other low- to medium-viscosity fluids inside cylinders 25.4 mm to 304.8 mm (1" to 12") in diameter. Features and Benefits • Adjustable nozzle air • High transfer efficiency • Self-adjusting PTFE packings • No mist or overspray Air Motor Pinion Gear Needle Needle Seat Rotor Air Tube Nozzle Rotor Fluid Inlet 1/8 NPT Actuating Air Input 1/8 NPT For use with: Accelerators Activators Lubricants Primers Solvents 7021649 (782RA Radial Spray Valve) Rotor length is 5.59 cm (2.2") and reaches into cylinders with a minimum inner diameter of 2.54 cm (1.0"). Includes fluid inlet fittings #7021499 and #7007038. Fluid body and rotor are hard-coat anodized aluminum. Each valve can be calibrated with the stroke reference knob for process control. Radial valves include fluid inlet fittings and two 1.5 m (5 ft) control air hoses with fittings to connect the valve to the ValveMate 7060RA controller.
