The GRACO 233772 is a mechanically operated back pressure regulator designed to limit supply pressure to a set value by opening and closing a valve in response to system pressure. Its intended use is within high-pressure fluid handling systems, ensuring stable and safe operation by maintaining back pressure within the specified range. Material is not specified in available documentation.

Key Features:

• Mechanical Back Pressure Regulator
• 233772
• Maximum permanent supply pressure: 3400 psi (23.5 MPa, 235 bar); Pressure range: 1300–3000 psi (9–20 MPa, 90–200 bar)
• Mechanically operated for reliable pressure control
• Designed for high-pressure applications
• Robust construction for demanding environments

Applications:
Used in industrial fluid handling systems where maintaining precise back pressure is critical, such as lubrication, hydraulic, and process control applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Ensure the system is depressurized before installation
• Follow torque specifications for all connections (e.g., torque to 10 N•m or 7.5 ft-lb as per manual)
• Inspect all seals and connections for integrity before operation
• Regularly check for leaks and proper pressure regulation
• Periodically inspect for wear or damage
• Replace seals and gaskets as needed
• Monitor system pressure to ensure regulator is functioning within specified range
