The GRACO 288117 is a pneumatic back pressure regulator designed for corrosion-resistant fluid control. It is constructed for use in demanding industrial environments, typically within fluid circulation systems, to maintain consistent upstream pressure regardless of flow demand. The regulator is intended for use with compatible GRACO equipment in applications requiring precise fluid pressure management.

Key Features:

• Pneumatic Back Pressure Regulator
• 288117
• 20 gpm (75 lpm)
• Maximum fluid inlet pressure: 300 psi (2.1 MPa, 21 bar); Regulated pressure range: 25–250 psi (0.017–1.72 MPa, 1.7–17.2 bar)
• 1-1/4 npt(f) inlet/outlet; compatible with GRACO fluid circulation systems
• Adjustable back pressure control
• Includes gauge port (1/4 npt(f)) for pressure monitoring
• Robust construction for industrial environments
• Designed for ease of maintenance and reliability
• Supports closed loop control for consistent system pressure

Applications:
Used in industrial fluid circulation systems, particularly in finishing and coating processes where precise upstream pressure control is required. Suitable for environments demanding corrosion resistance and high reliability.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety within GRACO equipment.
• Apply thread sealant to connections as recommended
• Torque screws in an alternating pattern: first to 30–33 in-lb (3.4–3.7 N•m), then to 68–72 in-lb (7.7–8.1 N•m)
• Lubricate moving parts as specified in the manual
• Ensure proper alignment and secure mounting
• Regularly inspect for leaks and wear
• Follow manufacturer-recommended maintenance intervals
• Use only compatible fluids and lubricants
