Norgren 8474400.0000.00000 Angle Seat Valve - 2/2 NC
Part Number: 8474400.0000.00000
Quick Summary
Norgren 8474400.0000.00000 Angle Seat Valve is designed for reliable flow control in demanding process lines. Operators often encounter contamination, leaks, and downtime when valves respond unpredictably to flow direction. The valve integrates a visual position indicator and dampened closing, while the stainless steel body and PTFE seat deliver durability in harsh media. This combination supports safe, compliant operation and fast diagnostics, enabling easier maintenance, reduced risk, and smoother integration with existing Norgren systems and automated lines.

Visual position indicator is standard. This provides immediate status visibility, reducing guesswork and unplanned stops on critical lines, which translates into less downtime and faster fault isolation in process automation. Dampened closing (closes against flow direction) reduces hydraulic shock and backflow, protecting lines from pressure surges and extending valve life in automated systems. Suitable for contaminated flow fluids. The PTFE seat seal and stainless steel body withstand challenging media, helping maintain performance with minimal maintenance. Vacuum capability up to 90% makes it suitable for low-pressure applications common in material handling and packaging lines. The 2/2 NC configuration plus G1 port size simplifies installation and wiring, enabling straightforward retrofit into existing manifolds and control circuits. Built to handle gases and liquids across a broad range, this valve supports long service life and predictable operation in harsh industrial environments.

FAQs
To install, ensure the manifold provides a standard G1 thread and compatible mounting pattern. Attach the valve body aligning the flow direction with system piping, then torque to the manufacturer’s specification. Connect control wiring for the 2/2 NC configuration and verify the visual position indicator is readable post-install. This setup supports straightforward retrofits into existing Norgren circuits with minimal downtime.
The valve is rated for -10 to 60 °C and 0 to 5 bar (0 to 73 psi). These ranges support gas and liquid media across typical process environments, enabling reliable performance in temperature- and pressure-variable applications. Always verify media compatibility with the PTFE seat and stainless steel body for your specific fluid and duty cycle.
Yes. The valve is designed for contaminated flow fluids, with a stainless steel body and PTFE seat that resist fouling and wear from dirty media. It also supports vacuum operation up to 90%, making it suitable for applications where low-pressure conditions and backflow control are critical, such as vacuum-assisted material handling and packaging lines.

Review the datasheet for detailed specifications, installation instructions, and any region-specific certifications. Always confirm current certifications with your regional compliance requirements before deployment.
The visual position indicator reduces diagnostic time, while the dampened closing minimizes flow-induced shocks that can shorten valve life. The PTFE seat and stainless steel body offer longevity in challenging media, lowering maintenance frequency and replacement costs. Overall, you gain higher line uptime, safer operation, and a faster payback period through reduced downtime and fewer unplanned interventions.
