The GRACO 187878 HOUSING, VALVE is a robust valve housing component designed for use in GRACO pneumatic back pressure regulators. It is typically constructed from durable materials suitable for industrial environments and is intended to house and protect internal valve mechanisms, ensuring reliable fluid control in high-pressure applications.

Key Features:

• Valve Housing
• 187878
• Maximum flow rate: 20 gpm (75 lpm) (when used with compatible regulator)
• Maximum fluid inlet pressure: 300 psi (2.1 MPa, 21 bar); Maximum air inlet pressure: 100 psi (0.7 MPa, 7 bar); Regulated pressure range: 25–250 psi (0.17–1.72 MPa, 1.7–17.2 bar)
• Used on GRACO 288117 back pressure regulator; 1-1/4 NPT(F) inlet and outlet
• Designed for ease of maintenance and reliability
• Suitable for high-duty cycle industrial applications
• Robust construction for long service life

Applications:
This valve housing is used in industrial fluid handling systems, particularly in applications requiring precise back pressure regulation, such as in lubrication, paint, and chemical transfer systems. It is suitable for use in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections (1-1/4 NPT(F))
• Follow torque specifications for secure installation
• Inspect O-rings and seals before installation
• Refer to the equipment manual for specific installation procedures
• Regularly inspect for leaks or wear
• Replace seals and O-rings as needed
• Keep housing clean and free from debris
