Radial Spray Valves

The 782RA radial spray valve uses a precision air motor and Low Volume Low Pressure technology to apply uniform coatings of lubricants, primers and other low- to medium-viscosity fluids inside cylinders 25.4 mm to 304.8 mm (1" to 12") in diameter.

Low Volume Low Pressure (LVLP) air is used to atomize the fluid, while a precision air motor drives a rotating air cap that produces the radial output. Rotor length is 5.59 cm (2.2") and reaches into cylinders with a minimum inner diameter of 2.54 cm (1.0").

High transfer efficiency with instant fluid cutoff at the end of the spray cycle ensures that coatings are applied evenly from startup to shutdown.

The complete valve system includes the 782RA spray valve, ValveMate 7160RA controller and fluid reservoir.
