Graco 237503 Back Pressure Regulator

Compatible Machines & System Applications

• Graco industrial fluid circulation systems
• Graco spray finishing systems
• Graco paint and coating circulation loops
• Graco pump-and-return fluid systems
• Graco industrial dispensing and coating equipment

This regulator is a system-level component and is selected based on pressure, flow, and plumbing requirements rather than a single sprayer model.

Graco 237503 Back Pressure Regulator Overview

The Graco 237503 Back Pressure Regulator is designed to maintain consistent upstream fluid pressure in circulation and spray systems. It helps stabilise fluid flow, reduce pressure fluctuations, and protect system components by regulating excess pressure in return lines.

This regulator is commonly installed in industrial coating and finishing systems where stable pressure is critical for consistent spray quality and reliable pump performance.

Key Functions

• Maintains consistent back pressure in fluid systems
• Improves spray pattern consistency
• Reduces pressure surges in circulation loops
• Protects pumps, hoses, and valves from pressure instability

Material & Design

• Durable construction suitable for industrial environments
• Manual adjustment for precise pressure control
• Compatible with water-based materials and catalysts
• Compact design for easy integration into existing systems
