The GRACO 26A169 is a kit containing a seat and PEEK dose valve, designed for use in GRACO fluid handling equipment. The kit is constructed with PEEK (polyether ether ketone), a high-performance engineering plastic known for its chemical resistance and durability. It is intended to ensure accurate and reliable dosing and sealing within GRACO mix manifolds and proportioning systems.

Key Features:

• Valve Seat Kit
• 26A169
• PEEK (polyether ether ketone)
• Designed for GRACO mix manifolds and proportioning systems (see manual for specific models)
• High chemical resistance due to PEEK material
• Designed for accuracy and reliability in dosing applications
• Ease of maintenance as part of a rebuild or repair kit
• Long service life and robust performance in demanding environments

Applications:
Used in GRACO fluid mix manifolds and proportioning systems for accurate dosing and sealing, particularly in applications requiring chemical resistance and reliable performance.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the equipment. Non-genuine parts may compromise system integrity and safety.
• Ensure the system is depressurized before installation
• Follow GRACO manual instructions for valve seat and dose valve replacement
• Check for proper lubrication of seals and o-rings as per manual recommendations
• Verify correct air pressure to valve actuators (minimum 75 psi, recommended 85 psi)
• Inspect for dirt or water in the air supply that may restrict valve actuation
• Regularly inspect valve seats and dose valves for wear or damage
• Lubricate seals and o-rings as recommended in the manual
• Replace worn or damaged parts promptly to maintain system performance
