Pegler Brass Non-Return Valve, 3", Heavy-Duty Check, Full-Bore

Size: 3" BSP threaded; Material: solid brass with a polished finish; Flow: high-flow capacity to minimize pressure drop; Closure: spring-type closure for effective backflow prevention; Corrosion resistance: designed for long-term use; Body: heavy-duty construction for demanding applications; Ideal for industrial plumbing and pumping installations.

Full-bore means the internal bore matches the pipe diameter, offering minimal obstruction to flow. This reduces pressure loss and helps maintain effective throughput in high-volume systems.

It's suited for industrial plumbing and pumping lines that require backflow prevention in 3" piping, where reliable, high-capacity shutoff is important.

Ensure the connection is clean and aligned with flow direction indicated on the valve. Use appropriate thread sealant or tape for BSP threads, hand-tighten, then snug with a suitable wrench without overtightening. After installation, test at low pressure for leaks before putting the system into service.

Yes. Use the valve within its intended industrial applications, ensure fluid compatibility, and follow local codes and standards. Check the flow direction arrow on the body to install it correctly, and avoid using with fluids that could corrode brass or compromise the seal.

Replace if you notice backflow, leakage around joints, reduced flow, visible corrosion, or a damaged spring. Regular inspection of the valve body and seals helps maintain reliable operation.

Periodically inspect for corrosion or damage, keep the external surface clean, and flush the line to remove debris. If you observe any signs of wear or leakage, replace the valve to maintain system integrity.

These options offer similar build quality with different pipe sizes to fit your system.

It's well-suited for industrial pumping installations, large-diameter water lines, and other high-flow systems where backflow prevention is critical. Always ensure the fluid is compatible with brass and suitable for NRV use.

The valve is described as heavy-duty with high-flow capacity, designed for demanding installations. Exact operating pressure rating isn’t specified here, so verify that your system’s pressures align with your project’s requirements and consult technical data if needed.

3" BSP threaded indicates the valve is designed to mate with 3-inch British Standard Pipe threaded connections. Ensure your piping components use BSP threads and choose matching nuts/fittings or adapters as needed to achieve a proper seal.
