The GRACO 113053 is a relief valve designed for use in GRACO industrial equipment. It is constructed from carbon steel and is intended to relieve fluid pressure at a fixed setting of 1600 psi (11 MPa, 110 bar). Its primary function is to protect equipment and operators by safely venting excess pressure from fluid systems.

Key Features:

• Relief Valve
• 113053
• Carbon Steel
• 1600 psi (11 MPa, 110 bar) fixed fluid relief pressure
• Designed for GRACO industrial equipment; 3/8 NPT (male) inlet, 3/8 NPT (female) outlet
• Fixed pressure relief setting
• Robust carbon steel construction for durability
• Standard NPT thread connections for easy integration

Applications:
Used in industrial fluid handling systems to prevent overpressure and ensure safe operation of pumps and dispensing equipment.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and safety in high-pressure applications.
• Apply thread sealant to all male threads during installation
• Install at the pump fluid inlet or outlet as specified in the equipment manual
• Ensure all connections are secure and leak-free before pressurizing the system
• Regularly inspect for leaks or signs of wear
• Replace the valve if it fails to relieve pressure at the specified setting
• Follow GRACO’s recommended maintenance schedule
