The GRACO 206831 is a check valve designed to allow fluid flow in one direction and prevent backflow. It is constructed with a stainless steel ball and nitrile rubber O-ring, intended for use in high-pressure fluid handling systems within GRACO equipment.

Key Features:

• Check Valve
• 206831
• Stainless steel ball, nitrile rubber O-ring, metal housing
• 3000 psi (21 MPa, 210 bar) Maximum Working Pressure
• 3/8 NPT(M) x 3/8 NPSM(F) swivel connections
• Upright mounting required for proper operation
• Robust construction for high-pressure environments
• Easy maintenance with replaceable O-ring and ball
• Reliable one-way flow control

Applications:
Used in high-pressure fluid transfer and lubrication systems, particularly where backflow prevention is critical. Suitable for industrial, mining, and agricultural equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO systems.
• Mount the valve in an upright position with the housing facing up for proper operation
• Ensure all connections are tight and leak-free
• Keep spare O-rings and balls on hand to reduce downtime during maintenance
