The GRACO 223824 is a corrosion-resistant, low shear mechanical back pressure regulator designed to control upstream fluid pressure in high-volume fluid handling systems. Constructed primarily from stainless steel, it is intended for use in applications requiring precise pressure control and compatibility with catalyst and waterborne materials, especially in industrial and sanitary environments.

Key Features:

• Back Pressure Regulator
• 223824 / 2 in Sanitary
• Stainless steel wetted materials, stainless steel membrane diaphragm
• 15.14 L/min (as listed, but product description also mentions 75.7 L/min; user query specifies 20 gpm, which is ~75.7 L/min—likely a discrepancy between marketing and technical specs; for this template, use 20 gpm as per user query)
• 200 psi (as listed), but user query specifies 300 psi max fluid pressure; for this template, use 300 psi as per user query
• Compatible with catalyst and waterborne materials
• Low shear diaphragm valve minimizes material degradation and color matching issues
• Large fluid passages for high-volume flow rates
• Highly wear-resistant and accurate responsiveness
• Closed-loop control maintains system pressure regardless of flow demand

Applications:
Used in industrial fluid handling systems requiring precise pressure control, especially for catalyst and waterborne materials in sanitary environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure all wetted surfaces are clean and free from debris before installation
• Follow GRACO’s recommended installation procedures for sanitary fittings
• Regularly inspect diaphragm and seals for wear and replace as needed
• Periodically check for leaks and pressure fluctuations
• Clean and inspect internal components during routine maintenance
• Use only compatible fluids to prevent corrosion and degradation
