The GRACO 208393 is a ball-type air shut-off valve designed for use in air supply lines. It is constructed from stainless steel and PTFE, making it suitable for use with catalyst, waterborne, and various finishing materials. Its primary function is to safely isolate or relieve air pressure in GRACO equipment, allowing for safer system operation and maintenance.

Key Features:

• Ball Valve / Air Shut-Off Valve
• 3/8 in. npt(m) x 3/8 in. npt(m)
• Stainless steel and PTFE
• Compatible with catalyst, waterborne, and various finishing materials; suitable for use in air supply lines for GRACO equipment
• Allows for safe isolation or relief of air pressure
• Reliable construction for demanding environments
• Ease of maintenance due to robust materials and design

Applications:
Used in air supply lines for GRACO equipment such as agitators, spray systems, and other pneumatic devices. Enables safe isolation of air pressure for maintenance or component replacement.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of your equipment.
• Install the air shut-off valve in the supply line to allow for safe isolation of air pressure.
• For best results, install an air line filter (e.g., part number 106148 for 3/8” npt) upstream to remove dirt and moisture.
• Consider installing an air line lubricator downstream for automatic air motor lubrication.
• Set the lubricator feed rate at 1 drop of oil per minute for high speed or continuous duty usage.
• Regularly inspect the valve for leaks or wear.
• Ensure the valve is free from debris and operates smoothly.
• Replace the valve if any signs of damage or malfunction are detected.
