The GRACO 238890 is a high-pressure fluid regulator designed for use in demanding industrial environments. It is constructed from stainless steel wetted materials, making it compatible with catalyst and waterborne materials. Its primary function is to regulate fluid pressure within GRACO equipment, ensuring consistent and safe operation.

Key Features:

• Spring-operated fluid pressure regulator
• 238890
• Stainless steel wetted materials, tungsten and carbide components
• 1.0 GPM (3.8 l/min)
• Regulated output: 500–3000 psi (3.4–21 MPa, 34–207 bar); Maximum inlet: 6000 psi (41 MPa, 414 bar)
• Compatible with catalyst and waterborne materials
• Corrosion resistant for long service life
• Tungsten and carbide materials for low wear
• Valve cartridge for quick cleaning and replacement
• Glycerin-filled gauge for accurate pressure reading
• Reduces downtime with easy maintenance

Applications:
Used in industrial fluid handling systems where precise pressure regulation is required, such as in paint, coatings, and lubrication applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise system integrity and void warranties.
• Torque mounting bolts to 140–160 in-lb (16–18 Nm)
• Ensure all connections are secure and leak-free
• Regularly inspect and clean the valve cartridge for optimal performance
• Follow all safety guidelines in the equipment manual
