The GRACO 19B727 is a medium pressure back pressure regulator cylinder designed for use in GRACO spray equipment. It is engineered to regulate and maintain consistent fluid pressure within the system, ensuring optimal performance and safety. The material is not explicitly specified in available documentation, but typical GRACO regulators of this type are constructed from robust metals for durability. Its intended use is to control and stabilize fluid pressure in medium pressure applications, supporting reliable operation of GRACO spray systems.

Key Features:

• Back Pressure Regulator, Cylinder
• 19B727 (20:1 ratio)
• Regulated fluid pressure range: 250–2000 psi (17–138 bar); Maximum fluid inlet pressure: 3000 psi (207 bar)
• Designed for GRACO medium pressure spray equipment
• Medium pressure operation
• Reliable pressure regulation

• Supports consistent system performance

Applications:
Used in industrial spray systems requiring medium pressure regulation, such as paint, coatings, or lubrication applications. Suitable for environments where maintaining consistent fluid pressure is critical for equipment performance and safety.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the spray system. Non-genuine parts may compromise safety and equipment longevity.
• Apply thread sealant to all threaded connections
• Torque connections to 60–70 ft-lbs (81–95 N•m) as recommended by GRACO
• Ensure proper alignment and secure mounting
• Follow all safety guidelines and manufacturer instructions during installation
• Regularly inspect for leaks or wear
• Replace seals and gaskets as needed
• Keep the regulator clean and free from debris
• Monitor system pressure to ensure proper function
