The GRACO 830351 is a fluid pressure regulator with an integrated dump valve, designed to control and regulate fluid pressure within GRACO equipment. It is constructed from durable materials including stainless steel (SS), tungsten carbide, acetal, PTFE, and nylon, ensuring compatibility with a wide range of fluids and resistance to wear. Its primary function is to maintain consistent fluid pressure and allow for quick flushing of the system.

Key Features:

• Fluid Pressure Regulator with Dump Valve
• 830351
• Stainless Steel (SS), Tungsten Carbide, Acetal, PTFE, Nylon
• 3.0 GPM (Gallons per Minute) at 100 psi inlet pressure (varies by model; some documentation lists 1.4 GPM at 50 psi regulated pressure, but 3.0 GPM is referenced for this part number in GRACO literature)
• Maximum Fluid Inlet Pressure: 250 psi (18 bar); Regulated Fluid Pressure Range: 3–100 psi (0.2–7 bar)
• Designed for use with GRACO fluid handling equipment; compatible with a wide range of fluids
• Integrated dump valve for quick system flushing
• Air-activated operation
• Quick flush design for easy maintenance
• Durable construction for long service life
• Reliable pressure regulation for consistent performance

Applications:
Used in industrial fluid handling systems where precise pressure control and quick system flushing are required, such as in lubrication, painting, and coating applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Follow the installation instructions provided in the GRACO manual (e.g., 308292 or 307941)
• Ensure all connections are secure and compatible with the specified thread types (e.g., 3/8 F, 1/4 F, 1/8 BSPP)
• Check for leaks after installation and during operation
• Regularly inspect and maintain the regulator and dump valve for optimal performance
