The GRACO C02021 is an automatic metering valve designed for precise dispensing of medium- to high-viscosity sealants and adhesives in non-hazardous locations. It is typically constructed from robust materials suitable for industrial environments and is intended for use within GRACO dispensing equipment to ensure accurate and reliable fluid delivery.

Key Features:

• Automatic Metering Valve
• Model 482-B
• Up to 4 cc per shot at moderate viscosity, up to 15 shots per minute (lower viscosities or smaller shots allow faster operation)
• Maximum fluid working pressure: 3200 psi (22.0 MPa, 220 bar)
• Designed for use with GRACO dispensing systems; compatible with medium- to high-viscosity fluids
• Precise dispense control
• Special snuffer action to prevent dripping or stringing
• 7/8–18 UNS externally threaded fluid inlet boss (C02021 only)
• 7/16–20 UNF mounting hole
• Reliable, easy-to-maintain design
• Suitable for non-hazardous locations

Applications:
Used for dispensing medium- to high-viscosity sealants and adhesives in industrial, manufacturing, and maintenance settings where precise application is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Connect the fluid supply line to the fluid inlet or to the external threads of the boss (C02021 only)
• Gradually apply fluid pressure while cycling the valve
• Increase pressure until the desired dispensing rate is attained and all air is purged from the fluid supply line
• To purge air, hold the valve higher than the fluid source with the hose on a gentle incline and cycle the valve repeatedly
• Always relieve pressure before servicing or disassembling the valve
