Check valve Sourcing 4115032, 1 1/4 in, backflow prevention valve

Sourcing check valve model 4115032 is a 1 1/4 inch inline backflow prevention valve designed to maintain unidirectional flow in fluid systems. It functions as a non-return valve for pipelines, protecting pumps, filters and other equipment from reverse flow. The valve is suitable for water and compatible liquids, and is intended for use in plumbing, irrigation and industrial circulation systems where reliable prevention of backflow is required.

Advantages

The valve provides reliable backflow prevention through a straightforward inline design that minimizes pressure loss while ensuring quick closure on flow reversal. Its 1 1/4 inch size fits common piping systems, allowing easy replacement or installation in existing lines. Constructed for fluid compatibility with water and similar media, the valve reduces the risk of damage to downstream equipment and helps maintain system hygiene by preventing contamination from reverse flow.

Suitable for

• Plumbing systems in residential and commercial buildings
• Irrigation lines for gardens, farms and greenhouses
• Circulation loops in water treatment and filtration setups
• Protection of pumps and compressors from reverse flow
• Industrial fluid systems handling water and compatible liquids

Key specifications

• Type: Inline check / non-return valve
• Nominal size: 1 1/4 inch connection
• Function: Backflow prevention, unidirectional flow control
• Compatible media: Water and compatible liquids (non-aggressive fluids)
• Typical applications: Plumbing, irrigation, circulation systems

How to use

Install the check valve inline with the flow direction indicated on the valve body so that fluid enters the inlet and exits the outlet. Ensure correct pipe connection method and sealing according to the pipe material and joint type used (threaded, soldered, or flanged as applicable). Verify that the valve orientation is horizontal or vertical as allowed by the manufacturer's installation guidance, and support adjacent piping to reduce mechanical stress on the valve. After installation, flush the line to remove debris before bringing the system to normal operating pressure and inspect for leaks.

Usage recommendations

To maintain reliable operation, avoid exposure to aggressive chemicals or media outside the valve's compatibility. Periodically inspect the valve and surrounding connections for wear, deposits or leakage; schedule maintenance according to system operating conditions. If sediment or particulate matter is present in the fluid, install appropriate filters or strainers upstream to prevent obstruction and ensure consistent backflow protection.
