The model MV-0180-PNM needle valve has been designed with a low-density plastic wetted chamber, so that the anaerobic resin does not come into contact with the metal body of the valve. Material is fed under pressure to the valve directly from its packaged container; the container bottle can be placed in an air pressure reservoir, top ported to the valve. An air pulse is delivered from a valve controller that actuates a solenoid attached to the needle seal, allowing the fluid to flow. When the air pulse is removed, a forward action spring returns the needle and closes the seal, shutting off the fluid. A 4-way air control can be connected to eliminate the reliance on spring pressure. Includes a stroke adjuster for final tuning of shot size.
