Norgren 8218401.0000.00000 Brass Angle Seat Valve - 2/2, G1
Part Number: 8218401.0000.00000
Quick Summary
Brass Angle Seat Valve from Norgren delivers high-flow control for gases and liquids in industrial automation applications. Engineers often struggle with contamination, vacuum compatibility, and the need for damped closures that prevent process disturbances. While the data does not list explicit CE, SIL, or IP certifications, these standards are typically relevant for valve performance in regulated environments, and the product’s brass body and PTFE seat support compliant operation under common industrial requirements. This valve’s 25 mm nominal size, 2/2 operation, and G1 port enable seamless integration into existing manifolds, while external pilot options and robust sealing contribute to reliable, cost-effective operation across your fluid-handling processes.

Feature → Business Impact → Application: The valve uses a brass body with PTFE seat seal, delivering high chemical compatibility and robust life in contaminated fluids, reducing maintenance frequency and downtime in dirty-process lines. This translates to lower lifecycle costs and predictable performance in food processing, water treatment, or chemical handling where cleanliness and reliability matter. Feature → Business Impact → Application: 25 mm nominal diameter with G1 port size supports straightforward installation in standard piping circuits, accelerating system upgrades and enabling rapid deployment in production lines that demand fast ROI and minimal commissioning time. Feature → Business Impact → Application: 2/2 valve operation with NO function provides straightforward control logic, simplifying PLC integration and enhancing control accuracy for pneumatic and fluidic automation tasks in packaging, labeling, or material handling. Feature → Business Impact → Application: Dampened closing and back-pressure tight operation improve process stability, reducing surge risk and extending actuator life in high-flow applications, especially where vacuum tolerance up to 90% is required, such as vacuum-assisted conveying or upstream sampling lines. Feature → Business Impact → Application: External pilot signal compatibility offers installation flexibility, allowing fluid or pneumatic pilots to drive the valve in tight spaces or multi-valve networks, which is advantageous for modular automation architectures in OEM equipment and turnkey automation projects.

FAQs
The 2/2 NO configuration provides a straightforward open/close control compatible with standard automation cycles, while the G1 port size aligns with common compact manifolds. This reduces the need for custom adapters and speeds up commissioning in OEM equipment and retrofit projects.
It handles gases and liquids across a wide range, with an operating temperature of -10 to 180 °C and a pressure range of 0 to 10 bar (0 to 145 psi). The brass body and PTFE seat seal contribute to chemical compatibility and reliable sealing under these conditions.
Yes. The design tolerates vacuum up to 90% and is rated for contaminated fluids, thanks to a robust brass body and PTFE seat seal. This makes it well-suited for vacuum conveyance, sampling lines, and processes where fluid cleanliness cannot be guaranteed.
Damped closing helps minimize pressure surges and wear on actuators, while the PTFE seat provides enduring sealing performance in dirty or aggressive media. Combined with reliable materials and a proven design, this reduces downtime and maintenance costs over the valve’s life.
By leveraging its high-flow capability, compatibility with external pilots, and robust seating, you can minimize valve-related bottlenecks, reduce energy use from over-sizing, and shorten commissioning time. These factors collectively improve throughput, reliability, and total cost of ownership in processing and packaging lines.
