The GRACO 233950 is a mechanical back pressure regulator designed to limit supply pressure to a set value, suitable for use with fluids of varying viscosities. It is constructed with robust materials for reliable operation within GRACO equipment, ensuring consistent system pressure and protection against overpressure in fluid handling systems.

Key Features:

• Mechanical back pressure regulator
• P20-RM DN1 (SKU:. 233950)
• Maximum permanent supply pressure: 290 psi (2000 kPa, 20 bar); Pressure range: 15–290 psi (100–2000 kPa, 1–20 bar)
• Suitable for low and high viscosity fluids; compatible with GRACO fluid handling systems
• Limits supply pressure to a set value for system protection
• Available with mechanical or pneumatic control (this model is mechanical)
• Responsive pressure control for consistent system pressure
• Reliable operation in demanding environments
• Ease of maintenance (general for GRACO regulators)

Applications:
Used in fluid handling systems where consistent pressure and protection against overpressure are required, such as lubrication, paint, and industrial fluid transfer applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure the regulator is installed in the correct orientation as per the equipment manual
• Check all connections for leaks before operation
• Set the pressure within the specified range for safe and efficient operation
• Regularly inspect and maintain the regulator to ensure continued performance
• Follow manufacturer guidelines for installation and maintenance
• Use only compatible fluids and pressures as specified
• Replace worn or damaged parts with genuine GRACO components
