The GRACO 19B729 is a piston-type air actuator designed for use with back pressure regulators (BPR) in GRACO fluid handling equipment. It is constructed from robust materials suitable for industrial environments and is intended to regulate and control fluid pressure by converting air pressure into mechanical force at a 20:1 ratio.

Key Features:

• Piston, Air Actuator, BPR
• 19B729, 20:1 ratio
• Compatible with GRACO medium pressure back pressure regulators and similar equipment
• Reliable piston actuation for precise pressure control
• Designed for ease of maintenance and serviceability
• Robust construction for industrial duty cycles

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

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the actuator
• Use appropriate tools and follow GRACO installation guidelines
• Check all connections for leaks and proper function after installation
• Regularly inspect and maintain seals and moving parts for longevity
