Dispensit 1052 and 1053 Valves 

Precision Dispense Valve
Positive displacement metering rod valves for low to high viscosity materials  

The Model 1052 & 1053 rod positive displacement valves are designed for volumetric shot-to-shot (1052) or bead (1053) dispensing of a wide variety of materials. 

  • For low to high viscosity materials with various wetted component configurations
    for abrasive filled, or corrosive materials
  • 1052 is a pneumatically-controlled valve with micrometer adjustable dispense volumes
    for accurate, repeatable shot dispensing
  • 1053 is a servo-driven valve for programmable, precise shot or bead dispensing
  • Pneumatic and electronic controls can be integrated for automated applications

PD44 

Patented Meter, Mix and Dispense Valve

For micro dispensing two-component materials

The Graco PD44 is specifically designed to dispense small amounts of water thin to paste viscosity materials from 0.005 cc’s to 5 cc’s. The metering rods are matched with machined seals for improved seal life.

  • Specifically designed to accurately dispense shots of two-component epoxies, urethanes, silicone and most reactive resin systems
  • Improved low viscosity spool design
  • Rod positive displacement metering
  • Precise mix ratio and shot repeatability
  • Eliminates cleaning and potential hardening of materials in the valve
