The GRACO 222405 is a high-pressure fluid back pressure regulator designed to control and maintain fluid pressure within GRACO equipment. It is constructed with tungsten carbide and plated carbon steel for durability and compatibility with solvent-borne materials. Its primary function is to regulate fluid pressure in lubrication and fluid handling systems, ensuring consistent performance and process control.

Key Features:

• Back Pressure Regulator
• 222405, 1/4 (f) x 1/4 (f)
• Tungsten carbide, plated carbon steel, PTFE, acetal homopolymer, cadmium and zinc-plated steel, stainless steel, chrome-plated stainless steel
• 3.5 gpm (13.25 liters/min) with 70 centipoise fluid at 75°F (23°C)
• Maximum fluid inlet pressure: 3000 psi (21 MPa, 207 bar); Regulated fluid pressure range: 0–1000 psi (0–7 MPa, 0–70 bar) as standard, but can be converted to 2000–3000 psi (14–21 MPa, 138–207 bar) with appropriate spring
• Solvent-borne materials
• Canadian Registration Number (CRN): Alberta – 0C04874.52, Ontario – 0C4874.5R1
• Laser-marked indication lines for easy pressure adjustment and process control
• Ergonomic adjustment knob
• Low wear and long life due to tungsten carbide materials
• Reliable performance in high-pressure environments

Applications:
Used in lubrication and fluid handling systems requiring precise pressure regulation, suitable for industrial, mining, and agricultural equipment.

Installation Notes:

• Use only genuine GRACO parts and accessories to ensure safety, reliability, and warranty compliance.
• Ensure proper alignment and secure connection of 1/4 NPT(f) fluid inlet and outlets
• Follow manufacturer’s instructions for spring selection and pressure range adjustment
• Regularly inspect for wear and maintain according to recommended schedules
