The GRACO 25R843 is a single-component, ball-seat dispense valve designed for high-pressure applications. It features a 1/4 inch NPT inlet and outlet, is constructed for ambient (non-heated) use, and is intended for precise, reliable dispensing of sealants and adhesives in industrial equipment.

Key Features:

• Ball/Seat Dispense Valve
• 25R843, 1/4 inch NPT inlet/outlet, 0in (000mm) nozzle
• Up to 5000 psi (34.5 MPa, 345 bar) for ball-seat valves
• Designed for use with GRACO iQ dispense systems and compatible with a wide range of sealants and adhesives
• Direct-mounted solenoid for fast, repeatable on/off operation
• High-pressure rating for demanding applications
• Easy maintenance with accessible internal components
• Reliable performance for industrial dispensing

Applications:
Used for precise dispensing of sealants and adhesives in industrial manufacturing, assembly, and maintenance applications. Suitable for environments requiring high-pressure, reliable, and repeatable dispensing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety in high-pressure dispensing systems.
• Ensure proper alignment of inlet and outlet ports
• Use appropriate tools for assembly and disassembly (e.g., 9 mm wrench for ball assembly removal)
• Inspect piston rod and ball assembly for wear or damage during maintenance
• Follow manufacturer guidelines for solenoid wiring and mounting
• Regularly inspect and replace worn seals and components
• Keep valve clean and free from debris
• Use only recommended replacement parts
