The GRACO 223617 is a fluid restrictor valve designed to manually adjust and restrict fluid flow to the gun in circulating systems. It is constructed from stainless steel (SST) for compatibility with catalyst and waterborne materials, and features a PTFE/elastomer hybrid diaphragm for durability and accurate responsiveness. Its primary function is to ensure uniform fluid suspension and eliminate material stagnation by circulating materials through the valve.

Key Features:

• Fluid Restrictor Valve
• 223617, 1/4 npsm(m) inlet/outlet, 3/8 twistlock outlet to gun
• Stainless steel (SST), PTFE/elastomer hybrid diaphragm
• 300 psi (21 bar) max
• Water-base fluids, catalyst and waterborne materials
• Manually adjustable flow settings at the gun
• Tamper-resistant adjustment knob to prevent operator interference
• Quick connection to spray guns using twistlock connector
• Circulates materials to ensure uniform suspension and prevent stagnation
• Durable construction for reliable performance

Applications:
Used in circulating systems for spray equipment to control and restrict fluid flow to the gun, ensuring consistent material application and preventing material settling or stagnation.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the equipment.
• Ensure proper alignment of inlet and outlet ports (1/4 npsm(m) inlet/outlet, 3/8 twistlock outlet to gun)
• Use appropriate adapters and couplers as specified in the manual
• Regularly inspect and maintain the valve and diaphragm for wear and proper function
• Keep spare cartridges (such as packing cartridges) on hand to reduce downtime
• Follow manufacturer guidelines for installation and maintenance
• Use only compatible fluids and materials as specified
• Periodically check for leaks and ensure all connections are secure
