The GRACO C02022 Automatic Meter Valve is an air-operated, single-acting metering valve designed for precise dispensing of medium- to high-viscosity fluids such as sealants and adhesives. It is constructed for use in non-hazardous locations and is typically made from robust materials suitable for industrial environments. Its intended function is to provide accurate, repeatable shot volumes in automated or semi-automated fluid dispensing systems.

Key Features:

• Automatic Metering Valve
• Model 482-C
• 0.2–4.0 cc per shot, up to 60 shots per minute (depending on fluid viscosity and shot size)
• Maximum fluid working pressure: 3200 psi (220 bar, 22.0 MPa)
• Designed for use with GRACO equipment and compatible with a range of medium- to high-viscosity fluids
• Double-acting air cylinder (in some configurations)
• Snuffer design to prevent dripping or stringing at the end of the dispensing cycle
• Reliable, repeatable shot volumes
• Easy to adjust and maintain
• Robust construction for industrial environments

Applications:
Used for precise dispensing of sealants, adhesives, and other medium- to high-viscosity fluids in manufacturing, assembly, and maintenance applications. Suitable for automated or semi-automated fluid dispensing systems in non-hazardous locations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Connect the fluid supply line to the 1/4 NPT(f) material inlet.
• Mount using the 7/16–20 UNF mounting hole.
• Gradually apply fluid pressure while cycling the valve to purge air from the supply line.
• Adjust pressure until the desired dispensing rate is achieved.
• For best results, hold the valve higher than the fluid source with the hose on a gentle incline during initial setup to help purge air.
• Regularly inspect for leaks and wear.
• Follow manufacturer guidelines for cleaning and maintenance.
• Relieve pressure before performing any maintenance.
